Description

Manipulator for power switchgear {THE MECHANISM FOR ELECTRIC POWER SYSTEM SPLITTING}

The present invention relates to a manipulator (mechanism; MECHANISM) for the power switching device, and more particularly, to engage or release the latch through the elastic force of the closing, opening spring generated by the motor and trip solenoid drive to rotate the toggle lever at a predetermined angle By opening and closing the contact of the circuit breaker, it relates to a manipulator for power switchgear for quickly or accurately separating or injecting the line failure section.

In general, in the transmission and distribution power system, which is a power system for supplying power to mechanical and electrical devices installed in industrial sites and homes, electrical accidents such as tree contact, lightning, vehicle accidents, wind, heat, etc. There is always a risk of a short circuit, a ground fault, a ground fault, etc. Since the fault current generated by the power system accident causes electrical or mechanical damage to the connected equipment, the faulty line section should be separated from the system promptly to fix the accident.

Therefore, it is desirable to install the power switchgear including protection relay and circuit breaker according to the capacity by analyzing the failure condition by the fault current in advance, and then immediately cut off or input the circuit after the line accident or the repair of the fault.

Wire breakers, disconnectors, line switches, load breakers and contactors, and other electrical machines provided on the high voltage line are provided with electrical contacts to connect and block the flow of electricity through the opening and closing of the contacts. In general, the blocking method through the contact allows the movable contact to be disconnected from the fixed contact automatically when the fault is detected at the movable contact and the fixed contact contacted in the normal state to cut off the current.

Here, the manipulator (mechanism) is responsible for separating or contacting the movable contact to the fixed contact. Manipulator is applied to power switchgear such as GLBS (Gas Load Break), ASS (Automatic Sectionalizing Switch), ALTS (Auto Load Transformer Switch), etc. Or SF ₆ insulation gas.

1 shows a flow of operating a conventional manipulator. The driving method of the conventional manipulator is a four-point operation of the toggle spring. That is, if there is no abnormality on the track, the manipulator is turned on, and the movable contact is fixed while the latch spring connected to the lever connected to the toggle spring is reached with the toggle spring reaching the dead point. In contact with the contact, current flows normally.

On the other hand, in the event of a fault on the track, the manipulator is moved to the shut-off mode. The toggle spring is reversed to reach dead point, and the latch is released by the interlocking lever so that the movable contact is separated from the fixed contact. Therefore, the fault current is cut off, and the electrical current and the mechanical device connected to the power system are prevented from entering the fault current, thereby providing electrical or mechanical protection.

However, in the conventional manipulator driving method, the dead spring stroke of the toggle spring requires a large driving force when the spring of the toggle spring is charged, and the driving step is complicated to ensure the switching time according to the input and opening of the manipulator in the power system. There was a problem.

In addition, the conventional manipulator takes a long time to transfer, and there is a problem in that an accident current flows into the electric device while the blocking is delayed, causing serious damage to the protection of the power system. In addition, since one toggle spring is used, stress reduction and cutting occurs due to frequent use, and thus, the manipulator can no longer execute the closing and opening operation.

The present invention has been made in order to solve the above problems, it is provided with a motor fixed to the plate and a plurality of gears and trip solenoid fastening of the latch by the reduction or reduction of the open spring and closing spring by the operation of the motor and the trip solenoid Or the release is made and the toggle lever by the fastening and release of the latch is rotated by a predetermined angle to drive the plurality of levers, links and shaft shafts connected to the main shaft of the toggle lever so as to space or contact the movable contact and the fixed contact, It is an object of the present invention to provide a manipulator for a power switchgear that accurately disconnects and connects line sections of a power system.

A plate-shaped stopper supporter 31 is fixedly installed between the second plate and the third plate, and a toggle lever 30 is installed on the stopper supporter 31.

Hereinafter, the operation of the first embodiment according to the manipulator for power switching device of the present invention configured as described above will be described in detail.

4 illustrates a state in which a latch of the manipulator according to the present invention is fastened so that a breaker for opening and closing a line is input when there is no abnormality in the power system, and FIG. 5 shows a breaker when a fault current flows due to an accident in the power system. The latch of the manipulator according to the present invention is shown in such a way that the latch is released.

As shown in FIG. 4, when there is no abnormality in the initial power system line, the manipulator is supplied to the power system to supply current to each electric and mechanical equipment. In this case, the latch 13 is engaged and the toggle arm 9 One end of the rod is inserted into the reinforcing plates 11 and 11 'between the link plates 10 and 10' so that one side is supported by the latch 13 and the other side is supported by the toggle arm stopper 12. And the toggle lever 17 is located in a state parallel to the support surface of the plate 1 is in a state in which the movable contact and the fixed contact of the breaker by the main shaft (17c) contacted. In the closed state, the open spring 19 is in the derating state and the closed spring 18 is in the reduced state, but the closed and open springs 18 and 19 are in a tensioned state so that the elastic force is applied.

When an accident occurs in the power system in the initial input state, the manipulator releases the latch 13 to switch to the open mode so that the movable contact of the circuit breaker falls from the fixed contact. Referring to the above switching process, if an accident occurs on a line, a DC current of 24V is applied to the trip solenoid 20 by detecting a fault current in a control panel (not shown) in which an IC chip is embedded. The trip solenoid 18 is excited and tripped and pulls the trip lever assembly 21.

6A and 6B illustrate a connection configuration and an operating state of the trip solenoid 20 and the trip lever assay 21, respectively. As shown in FIG. 6B, the trip solenoid 20 moves along the guide groove 21a by pulling one end of the tripping link of the trip lever assay 21, and the other end moves in the opposite direction through the hinge shaft installed on the third plate. The spring lever 16 is pushed. The trip solenoid 20 operating the trip lever assembly 21 is restored to the original position in the retracted mode, and the trip lever assembly 21 also places the spring lever 16 and moves to the original position.

Next, the spring lever 16 is rotated to a predetermined range by the stopper pin 14 inserted into the torsion spring 15 and the engaging hole 16a, and thus the latch 13 is also rotated in the same radius to be released from the fastening state. And the toggle arm 9 is instantaneously rotatable.

Next, the rotating spring 6 and the toggle lever 17, the rotating spring 6, and the closing spring 18 and the open spring 19, which are fastened and fastened to the tank, are contracted by the elastic force retained and the rotating shaft 6 And pull the toggle lever 17. At this time, the input spring 18 also acts to pull the rotary shaft 6, the main action of pulling the rotary shaft 6 and the toggle lever 17 to the open mode at the same time is the opening spring (19).

Accordingly, the rotation shaft 6 rotates in the forward direction (Fig. 4 counterclockwise) and the toggle lever 17 also rotates in the forward direction to the position point of the toggle stopper 30. In addition, the link plates 10 and 10 'also rotate so that one end of the link plate connected to the toggle arm 9 is moved in the reverse direction (Fig. 4 clockwise) so that the toggle arm 9 in the released state is linked to the link plates 10 and 10'. Deviate outward from As soon as the toggle arm 9 is released from the latch 13, the latch 13 and the spring lever 16 are restored to their original positions by the elastic force of the torsion spring 15.

In addition, the main shaft 17c is rotated to a predetermined range at the same time as the toggle lever 17 is rotated to separate the movable contact of the breaker from the fixed contact. Sparks or arcs that occur instantaneously when the movable contact is spaced from the stationary contact are covered by enclosed insulation gas or insulating oil.

In the above process, the manipulator terminates the switching from the input state to the open state, and the open state of the manipulator is shown in plan view in FIG. 5.

FIG. 5 illustrates a case in which the manipulator is switched to an open state in FIG. 4.

As shown in FIG. 5, when the power system line has a failure, the manipulator is in a shut-off state for repairing a failure. In this case, the latch 13 is released so that one end of the toggle arm 9 is removed from the link plates 10 and 10 '. The toggle lever 17 is rotated at a predetermined angle on the bottom horizontal surface of the plate 1.

When the fault in the power system is repaired, the manipulator must be switched to the input state so that the current is supplied by contacting the breaker's movable and fixed contacts. In the above-described switching process, first, when the current flows normally by comparing and detecting the current in the control panel having the IC chip, the driving voltage of DC 24V is applied to the motor 2. Since the control panel detects an abnormality of the current, it is possible through a known technology such as a current transformer, and thus detailed description thereof will be omitted.

Next, the motor 2 rotates at a high speed in the forward direction (Fig. 5 counterclockwise), and the low speed and high torque generated through the reduction gear 3 are transmitted to the driving pin 4. The rotating drive pin 4 rotates the drive shaft 4 and the drive pin 4 'located on the other side plate 1 connected to the connecting arms 5 and 5' in the counterclockwise direction. Therefore, since the rotating shaft 6 rotates in the counterclockwise direction, the open spring 19 and the closing spring 18 in the open state proceed simultaneously to the compact state, and one end of the toggle arm 9 connected to the rotating shaft 6 is Rotate counterclockwise and the other end is clockwise. The link plates 10 and 10 'hinged to the other end of the toggle arm 9 and the spacer are rotated counterclockwise.

The toggle lever 17 coupled to the other ends of the link plates 10 and 10 ′ is spaced apart from the toggle lever stopper 30 by the rotation of the link plates 10 and 10 ′ and rotates clockwise to allow the plate 1 to rotate. It comes close to the bottom horizontal plane of the closing spring 18 and the opening spring 19 becomes more compact. When the rotation shaft 6 is further rotated, the end of the toggle arm 9 is inserted into the link plates 10 and 10 'to be adjacent to the latch 13.

Next, when the rotary shaft 6 is located at the top, the opening and closing springs 18 and 19 are stretched to the maximum to reach the dead point.

Next, as the rotary shaft 6 passes through the vertex, and the closing and closing springs 18 and 19 pass through the dead center, the toggle arm 9 is instantaneously driven by the elastic force and is provided with a spring lever installed on the link plates 10 and 10 '. 16 and the latch 13 are rotated and inserted into the latch 13 so as to be supported and fixed by the toggle arm stopper 12. The engagement of the toggle arm 9 and the latch 13 upon release is shown in detail in FIGS. 7A, 7B and 7C.

7A is a toggle arm release state diagram of the latch, FIG. 7B is a state diagram in which the latch is switched from the released state to the engaged state, and FIG. 7C is a state diagram in which the latch is completely switched to the engaged state. As shown in FIG. 7B, when the end of the toggle arm 9 introduced into the cutting end portion of the latch 13 comes into contact and is pushed, the end of the toggle arm 9 passes through the cutting surface of the latch 13 which is rotated. It is fixed to the circumferential surface of (13). On the contrary, when the circumferential surface of the latch 13 is rotated by the spring lever 16 and separated from the end of the toggle arm 9, the toggle arm 9 is released from the latch 13 and is released.

Next, the toggle lever 17 rotates the main shaft 17c while completely descending to the horizontal bottom surface of the plate 1 to bring the movable contact into contact with the fixed contact, so that the breaker safely conducts current to the electric and mechanical equipment.

In the above process, the manipulator is terminated in the switching mode from the shut-off state. 4 shows a closing state of the manipulator, and the description of the closing state is omitted since the description of the closing state is as described above. In this embodiment, it was confirmed that the transfer time of opening and closing of the manipulator was 4.5 to 5 sec.

Each component of the first embodiment of the manipulator for power switching device of the present invention is preferably made of a material of the following manufacturing method to prevent malfunction due to corrosion and deformation.

The toggle arm is a precision casting manufacturing method that maintains the strength and hardness when tightened with the latch so that there is no deformation. The latch is processed with a stainless steel extruded rod in a precision automation line to maintain the toughness (toughness) of the material.

The other end of the toggle lever 117 is formed with a main shaft 117b rotatably penetrating through the second and third plates, and the main shaft 117b has a lever connected to the shaft shaft for driving the contact of the power switch. It is fixed (not shown).

In the lower portion of the toggle lever 117, the input shaft 116 is installed to be rotatable through the second and third plates to fasten or release the end of the toggle lever 117, and the input shaft 116 is toggled. A catching groove 116a is formed to facilitate the movement of the end of the lever 117. In the state that the power switch is open, the input shaft 116 is rotated with respect to the horizontal plane at a predetermined angle so that the end of the toggle lever 117 is caught on the circumferential surface of the rear surface of the locking groove 116a, the main shaft 117b To form a comb surface so that the end of the toggle lever 117 to rotate around the pointed shape was made to move the locking groove 116a well and to easily bind to the circumferential surface.

When switching from the open state to the input state, a significant elastic force is applied to the input spring 118 connected to the rotary shaft 106 and the toggle lever 117 by the driving of the rotary shaft 106, and the toggle lever 117 is fast due to the elastic force. The operation of the operation of the manipulator occurs by rotating the input shaft. In order for this operation to occur, the input shaft 116 is rotated so that the end of the toggle lever 117 hanging on the input shaft 116 is released along the locking groove 116a. Should be.

Therefore, one side of the input shaft 116 protruding through the third plate is provided with an input lever 115 that is integrally rotated, and the target interlocking portion 114 for rotating the input lever 115 during the feeding operation is also provided. It is provided in the outer surface of a 3rd plate.

The target linkage unit 114 is composed of a target lever 111, a lever connecting member 112, a target spring 113. The target lever 111 is bent at a predetermined angle with respect to the center, the center of which is hinged to the outer surface and the connecting member of the third plate, and once the rotational force of the touch lever 109 during the rotation of the rotary shaft 106 The target lever projection 111a for rotating the target lever 111 is formed to receive the received.

When the touch lever 109 presses the target lever protrusion 111, the portion of the target lever 111 and the lever connector 113 are raised so that the target spring 113 has elastic force, and the touch lever 109 is the target lever when opened. When the non-contact with the protrusion 111, the target lever 111 is restored by the elastic force, the input shaft 116 is returned to its original position.

In addition, when switching to the input state, the toggle lever 117 is released by interlocking the touch lever 109, the target interlocking unit 114, the input lever 115, and the input shaft 116, and the elastic restoring force of the input spring 118 is released. By the moment the toggle lever 117 is rotated at this time, the movable contact is connected to the main shaft 117b formed at one end of the toggle lever 117 through the shaft shaft occurs, so the toggle lever 117 to prevent this The stopper support 131 of the plate type is fixedly installed between the second plate and the third plate so as to limit the rotation to a predetermined range, and the toggle stopper 130 is installed on the stopper support 131.

On the other hand, when the rotary shaft 106 is driven and passes through the dead point where the open spring 119 is maximized, the rotating shaft 106 is quickly rotated to its original position by the elastic force held by the open spring 119, thereby switching to the open state. A latch 120 for limiting the rotational drive of the rotary shaft 106 is rotatably installed through the first and second plates so that the closing operation is continued for a predetermined time until the opening operation due to an accident occurs.

The latch 120 has a protrusion 120a formed therein, and the protrusion 120a is caught by a driving end of the trip solenoid 121 installed on the second plate, thereby latching 120 by the operation of the trip solenoid 121. One end surface of the connecting arm 105 connected to the rotary shaft 106 by the rotation operation of the) is pressed. In addition, by cutting one surface of the latch 120 so as to have a cutting surface flat with a semicircular circumferential surface, the connecting arm 105 is moved along the cutting section when the latch 120 is released. It is configured to reduce the friction between the latches (120).

Hereinafter, the operation of the second embodiment according to the present invention configured as described above will be described in detail.

FIG. 10 is a configuration diagram showing a state in which a second embodiment of the manipulator for power switching device of the present invention is input, and FIG. 11 is a configuration diagram showing a state in which a line failure section is blocked by a second embodiment of the manipulator for power switching device of the present invention. .

As shown in FIG. 10, when there is no abnormality in the initial power system, the manipulator is turned on and supplies current to each electric and mechanical device. In this case, the circumferential surface of the latch 120 presses the connecting arm 105. It is a state which limits the drive of the rotating shaft 106. FIG.

The rotating shaft 106 is pushing the link plates 110 and 110 'by applying a constant force to the ends of the link guide grooves 110a and 110'a of the link plates 110 and 110', that is, the side where the toggle lever 117 is located. And the toggle lever 117 exited from the closing shaft 116 is stopped by the toggle lever stopper 130 and the closing spring 118 is in a state in which the elastic force is finely hung.

On the other hand, the open spring 119 is tensioned as much as possible after passing through the dead point, and the state in which the latch 120 does not pressurize the connecting arm 105 has an elastic force for rotating the rotation shaft 106 to its original state. In addition, the touch lever 109 pushes the target lever protrusion 111a to maintain the cutting surface of the engaging groove 116a of the closing shaft 116 close to parallel to the bottom horizontal plane, and the elastic force is applied to the target spring 113. (See FIG. 12)

If an accident occurs in the power system, the manipulator must be released to the open mode by releasing the latch 120. When the switching process is described first, when DC24V is applied to the trip solenoid 121 in the control panel (not shown), the trip is tripped. The solenoid 121 is excited and tripped, and the latch 120 rotates clockwise by pulling the protrusion 120a of the latch 120 momentarily (see FIG. 10).

Next, the connecting arm 105 is rotated along the cutting surface of the latch 120, the connecting arm 105 and the rotating shaft 106 is rapidly rotated clockwise by the elastic force held by the open spring (119). The rotary shaft 106 strongly pushes the ends of the link guide grooves 110a and 110'a to drive the link plates 110 and 110 'at a high speed in the direction in which the toggle lever 117 is located. One end of the toggle lever 117, which is caught in the link guide grooves 110b and 110'b formed at the other end by driving the link plates 110 and 110 ', is also instantaneously counterclockwise along the locking groove of the closing shaft 116. It is pushed hard and caught on the circumferential surface of the input shaft 116.

When the connecting arm 105 passes through the latch 120, the trip solenoid 121 recovers to its original position in the retracted mode, and the latch 120 also rotates to the original position.

Next, the main shaft 117b of the toggle lever 117 is also rotated counterclockwise to space the movable contact from the fixed contact.

The touch lever 109 connected to the driving pin 104 'is also rotated clockwise by the rapid clockwise rotation of the rotation shaft 106 while the target lever protrusion 111a is being pressed, so that the touch lever protrusion 111a is provided. In this case, the target lever 111 is rotated clockwise to recover the original position by the restoring elastic force of the target spring 113. The pressure applied to the input lever 115 through the lever connector 112 is also applied. As a result, the closing shaft 116 is rotated counterclockwise to return to its original position (see Fig. 12).

Therefore, the end of the toggle lever 117 moved along the engaging groove 116a installed in parallel with the horizontal bottom surface in the closed state is rotated at a predetermined angle of the input shaft 116, so the circumferential surface of the closing shaft 116 Is caught. Of course, the link plates 110 and 110 'by the clockwise driving of the rotation shaft 106 by the open spring 119 push the toggle lever 117 to the toggle lever 117, compared with the time when the closing shaft 116 returns to the original position. Opening operation occurs smoothly only when the time passing the end of the fastening groove 116a is fast. Therefore, precisely controlling the distance between the target linkage 114 and the input lever 115, the elastic force of the open spring 119 and the width of the link guide grooves 110a, 110'a, 110b, 110'b, etc. desirable.

In the above process, the manipulator terminates the switching from the input state to the open state, and the open state of the manipulator is shown in plan view in FIG. 11.

As shown in FIG. 11, the toggle lever 117 is engaged with the closing shaft 116 while the latch 120 releases the connecting arm 105, and the touch lever 109 is a touch lever. It is not in contact with the projection 11a. The connection state of the touch lever 109 and the target linking unit 114 according to the input and opening of the manipulator is shown in detail separately in FIG. 12 and will be described later.

If the accident is rectified in the power system, the manipulator should be switched to the input state. To describe the switching process in detail, first, when the voltage of 24V is applied to the motor 102 in the control panel, the motor 102 is rotated in the forward direction (Fig. 11 clockwise). Accordingly, the connecting arms 105 and 105 'connected to the driving pins 104 and 104' are also rotated so that the rotating shaft 106 rotates clockwise slowly along the link guide grooves 110a and 110'a. One end point of the link guide grooves 110a and 110'a is reached. When the rotation shaft 106 further rotates, one end of the link guide grooves 110a and 110'a is pushed to lift the link plates 110 and 110 'in a clockwise direction. The touch lever 109 connected to the driving pin 104 'is rotated clockwise as the rotary shaft 106 is driven to gradually approach the target lever protrusion 111a. (See FIG. 12).

In addition, with the rotation of the rotary shaft 106, the injection spring 118 connected to the rotary shaft 106 and the toggle lever 117 and the open spring 119 connected to the rotary shaft 106 and the second plate are contracted to increase the elastic force. .

Next, when the touch lever 109 is further rotated to contact the target lever protrusion 111a and presses the touch lever protrusion 111a to rotate counterclockwise, the lever connector 112 connected to the other end of the target lever is raised. And rotate the input lever 115 clockwise. Therefore, the input shaft 116 is rotated clockwise at a predetermined angle parallel to the horizontal bottom surface.

Next, when the rotating shaft 106 is further rotated, the closing spring 118 and the opening spring 119 are further condensed and the closing shaft 116 is rotated so that the end of the toggle lever 117 is released from the closing shaft 116. At the moment, due to the elastic force of the closing spring 118 is pulled sharply toward the rotating shaft 106, the main shaft 117b of the toggle lever 117 is rotated in the clockwise direction, the movable contact and the fixed contact of the power switch This comes into contact with energization.

At the same time, the open spring 119 is maximally tensioned as it passes through the dead point, and the rotational axis 106 also passes through the vertex so as to rotate clockwise by the elastic force of the open spring 119, but is installed on the upper portion of the connecting arm 105. Since the 120 temporarily fixes the connecting arm 105, the rotation shaft 106 cannot be rotated any more so that the input state of the manipulator is continuously maintained.

In the above process, the manipulator terminates the switching from the blocking state to the closing state.

10 illustrates an input state of the manipulator, and a description of the input state is omitted since the description of the input state has been described above.

Figure 12 shows the operating state of the touch lever and the target linkage and the input lever in the input state and the open state of the second embodiment of the manipulator for the power switch device of the present invention, in particular the dotted line shows the input state.

As shown in the drawing, the touch lever 109 presses the target lever protrusion 111a as much as possible so that the input lever 115 is rotated clockwise so that the toggle lever 117 is pulled out of the input shaft 116. In the open state, the touch lever 109 is spaced apart from the target lever protrusion 111a so that the toggle lever 117 is fastened to the input shaft 116.

In addition, the second embodiment according to the manipulator of the power switch device according to the present invention, as in the first embodiment, the parts with frequent contact and abrasion, for example, a device such as a latch, are processed and manufactured by using stainless bar and plate, and thus malfunction due to deformation and corrosion. It is preferable to prevent the other components also can be prevented from deformation and corrosion of the manipulator in the case of manufacturing the stainless steel bar and plate.

For reference, the manipulator for the power switch device according to the present invention is not limited to the above specific embodiments, but may be modified within the technical scope of the detailed description, claims, and drawings.

Manipulator for power switchgear device of the present invention acting as described above is a fully automatic wiring system by quickly separating the line accidents occurring in the power system with a faster switching time than the one-touch input of the toggle-latch method, the operation method of the spring dead-point method. KODAS (Korean wiring automation) has an advantage that can be easily applied.
