Description

Novel high-voltage switch operating mechanism

Technical Field

The utility model relates to a novel high-voltage switch (3.6kV ~ 40.5kV) operating mechanism, especially the operating mechanism for vacuum switch who has isolator.

Background

At present, the known high-voltage switch operating mechanism is characterized as follows:

firstly, when the switch is switched on and switched off, an electromagnetic release is needed to drive an armature to move, and the armature impacts a tripping plate to drive a switch-on or switch-off half shaft to rotate, so that energy storage holding or switch-on holding is released, and the switch is switched on or switched off under the action of a switch-on spring or a switch-off spring. Due to the action of a closing spring or an opening spring (including a contact pressing spring), the rotation resistance of a closing half shaft and an opening half shaft is very large, the armature is required to have very large inertia to impact the movable half shaft to rotate, meanwhile, the switch needs very short time to complete closing or opening, and therefore a stronger magnetic field needs to be generated, the coil of the electromagnetic trip absorbs very large electric energy to drive the armature to move faster, the mass of the armature cannot be increased, and the moving speed, the volume and the manufacturing cost are influenced. In order to provide enough power for the coil of the electromagnetic release instantaneously, a high-power supply is required to be configured, and in order to ensure that the power supply is uninterrupted, a large-capacity storage battery or a super capacitor is required to be configured to ensure that the instantaneous high-power supply can be uninterruptedly provided.

Secondly, because the high-voltage switch is not operated to be opened and closed frequently, the storage battery is only in a floating charging state for a long time, and current is released rarely, so that the battery is easy to age, and when the high-voltage switch needs to work, enough current can not be released possibly, and normal action is influenced.

And the storage battery needs to be maintained, has large volume, more auxiliary equipment and high manufacturing cost, and brings great acquisition and maintenance cost.

The battery has limited service life, so that a large amount of discarded batteries are eliminated every year, the recovery cost is high, the environmental pollution is serious, and great environmental pressure is caused to the society.

In order to ensure safety, the coil of the electromagnetic release needs to be normally closed and opened under the condition of the lowest voltage, and can be normally closed and opened under the highest voltage without burning loss. The magnetic field is weak in low voltage, the motion speed of the armature is low, the magnetic field is strong in high voltage, the motion speed of the armature is high, although the switch can be driven to be switched on or switched off finally, the time required by the whole switching-on or switching-off is in a large change range, the protection on power lines and equipment is very unfavorable, particularly, the switching-on and switching-off time is long in low voltage, the interval time between the switching-off and the reclosing and the short circuit duration time are too long, and the safety of a power grid is influenced. Ideally: the switching-on and switching-off time is as short as possible and stable and unchanged, so that the staged tripping is realized by setting shorter reclosing starting time and shorter time difference between upper and lower stages, and the time and range of fault power failure are reduced, which is a problem that a power distribution network has never been solved.

And electrical and mechanical double interlocking is needed between the switches (including the circuit breakers and the load switches) and the isolating switches, the mechanical interlocking is complex and not reliable enough, and particularly, parts can be damaged when forced misoperation occurs.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect and the problem that prior art exists, the utility model provides a close, the separating brake electric current is little, closes, the separating brake time is short, closes, the separating brake time variation scope is little, has isolator operating mechanism, interlocks reliable a novel high-voltage switch operating mechanism between switch and the isolator.

In order to achieve the above object, the utility model provides a following technical scheme:

this novel high voltage switch operating mechanism includes: a cam; a brake-separating energy-storing release; closing an energy storage release; a brake-separating energy-storing release pressing plate; closing energy storage release pressing plates; closing the energy storage driving plate spring; the brake separating energy storage driving plate spring; closing an energy storage shaft; a brake separating energy storage shaft; closing an energy storage lever; a brake-separating energy storage lever; an isolating switch operating shaft; the isolating switch operates a pressure spring; an isolation switch operating motor with a bi-directional clutch; an interlocking connecting piece; an isolation switch interlock lever; the isolating switch interlocks the crank arm; a switch interlock lever; a switch interlock pin, etc.

The novel high-voltage switch operating mechanism is characterized in that the novel high-voltage switch operating mechanism further comprises: when the switch is switched on and stored with energy, the operating mechanism firstly stores energy for the switching-on energy storage release through the switching-on energy storage lever, the switching-on energy storage driving plate spring, the switching-on energy storage shaft and the switching-on energy storage release pressing plate. When the switch is in brake-off, the switch is linked with the brake-off energy storage lever, the brake-off energy storage driving plate spring, the brake-off energy storage shaft and the brake-off energy storage release pressing plate to store energy for the brake-off energy storage release. When the closing and opening energy storage release stores energy in place, the energy storage driving plate spring is pressed to deform to absorb the overshoot, so that reliable energy storage is ensured, and parts are not damaged. The closing and opening energy storage release adopts a permanent magnet to keep an energy storage position, when the release is carried out, a coil generates reverse magnetic flux through small current to counteract partial magnetic flux generated by the permanent magnet, so that the magnetic flux is reduced, the suction force is insufficient, and an armature leaves a stop iron under the action of a conical pressure spring and starts to move to impact a releasing plate to enable a switch to be closed or opened. The isolating switch interlocking lever and the isolating switch interlocking crank arm form an included angle of 90 degrees in a locking state, and the isolating switch interlocking lever and the isolating switch interlocking crank arm are not easy to be forcibly operated and damaged. The switch interlocking rod and the switch interlocking pin form an included angle of 90 degrees in a locking state, and the switch interlocking rod is not easy to be forcibly operated and damaged.

Advantageous effects

Firstly, the energy storage release can release the armature to act by needing very small current, thereby greatly reducing the power supply capacity, particularly reducing the battery capacity, and having extremely remarkable economic benefit and environmental protection benefit;

the capacity of a power supply for driving the separating brake energy storage release is greatly reduced, a voltage transformer or a transformer and a storage battery thereof do not need to be configured independently to provide power, and the separating brake energy storage release can work only by providing a power supply with extremely small capacity by the current transformer, so that the manufacturing cost is reduced, the switch outlet is ensured to be short-circuited, and the protection action can be still performed when the power supply voltage is completely still available, and the safety of a power grid is improved;

the energy released by the energy storage release is only potential energy of the spring, the potential energy is basically constant (as long as the structure and the material of the spring are consistent) and has no relation with voltage applied by the coil, the movement speed of the armature is also independent of the voltage of the applied coil, and the armature impacts the trip plate at constant inertia (speed), so that the closing and opening time of each switch is very short and basically constant, and the protection of a power grid is very favorable;

driving the closing energy storage release or the separating energy storage release to store energy when the switch is switched on and switched off, and arranging an elastic closing energy storage driving plate spring or separating energy storage driving plate spring in the middle, so that the damage to parts due to the fact that transmission is not stopped when energy storage is in place (an armature is in contact with a stop iron) is avoided, and meanwhile, the overshoot is ensured to reliably store energy each time;

the interlocking pieces of the switch and the isolating switch are mutually stopped at 90 degrees in a locking state, and are not easy to be pressed and bent to be damaged;

the isolating switch with the bidirectional clutch operates the motor, so that the operation is labor-saving, safe, simple and reliable;

the switch mechanism and the isolating switch mechanism are integrated, the interlocking is simple, and the manufacturing cost is low.

thirdly, the closing energy storage release stores energy for the closing energy storage release (in a release state) (65) through a transmission mechanism by means of half-circle stroke of idle rotation of a cam (47) in the switch energy storage process;

the opening energy storage release stores energy for the opening energy storage release (release state) (109) through the transmission mechanism when the switch opens;

the isolation interlocking crank arm (93) and the isolation interlocking rod (91) form an included angle of nearly 90 degrees in an interlocking state, see fig. 12;

sixthly, the switch interlocking rod (96) and the switch interlocking pin (98) form an included angle of nearly 90 degrees in an interlocking state, which is shown in figure 16;

and magnetic flux generated by the permanent magnet (113) overcomes the tension of the conical pressure spring (122) to keep the armature (110) and the stop iron (119) to be attracted, and when the coil (117) generates reverse magnetic flux through current, the attraction is not enough to overcome the tension of the conical pressure spring (122) to release potential energy of the spring, and the potential energy of the spring is changed into kinetic energy to drive the armature to move.

2. The working principle of the energy storage release is as follows:

in the non-charged state (see fig. 17), the conical spring has only a pre-compressed potential energy, which is relatively limited. Referring to fig. 18, in order to release the closing energy storage release (65) and the opening energy storage release (109), because of the two permanent magnets (113), the magnetic flux path generated by the S poles on the inner side (or both on the outer side) is shown by the curve with the arrow, because the air gap (120) is relatively large, the magnetic resistance is relatively large, the magnetic flux is relatively small, and the attraction force between the armature (110) and the blocking iron (119) is not enough to overcome the pulling force of the tapered pressure spring (111) to pull together. Referring to fig. 20, when the armature (110) is compressed by an external force until it contacts with the stop iron (119) to form a contact surface (123), the reluctance of the magnetic circuit is small, the magnetic flux becomes large, the attraction force is increased, the conical pressure spring (compressed state) (122) cannot overcome the attraction force generated by the magnetic flux to separate the armature (110) from the stop iron (119), and the armature (110) is firmly attracted to the stop iron (119). When a magnetic field generated by the coil (117) after passing through a certain direction of current is opposite to the direction of a magnetic field generated by the permanent magnet (113), the total magnetic flux is reduced, the attraction force is also reduced, when the pulling force of the conical pressure spring (in a compressed state) (122) cannot be overcome, the armature (110) is released, and under the action of the conical pressure spring (in the compressed state) (122), the armature strikes a closing energy storage release tripping plate (63) or a separating energy storage release plate (7) to close or separate a switch. Since the impact inertia is mainly related to the conical pressure spring (122) in a compressed state and is not related to the voltage applied by the coil (117), as long as the characteristics of the conical pressure spring (111) in a pre-compressed state and the conical pressure spring (122) in the compressed state are consistent, the inherent opening time of the switch is basically constant and relatively quick (large potential energy can be stored due to the conical spring), but the energy consumed by a control power supply is very limited, and compared with a conventional electromagnetic release, the impact inertia is only about 4% of the impact inertia.

3. Switching on the switch and the isolating switch:

the operating mechanism with the isolating switch operating mechanism ensures that the isolating switch is firstly closed and then the switch is closed when the switch is closed, so the isolating switch is firstly closed.

Closing process of isolating switch

When the disconnecting switch and the disconnecting switch are confirmed to be in the switching-off position, the disconnecting switch operating handle (18) is manually operated to rotate clockwise (see fig. 1), and then, under the driving of the disconnecting switch linkage connecting lever (72) rotating anticlockwise around the disconnecting switch operating shaft (17), the disconnecting switch operating shaft (17) is driven to rotate actively after the disconnecting switch operating pressure spring (74) passes through the middle (the centers of the disconnecting switch operating shaft (17), the connecting shaft 32 and the supporting shaft 77 are on the same straight line) until the switching-on is in place (see fig. 2 and 4). Or, the output shaft (31) of the disconnecting switch operation motor rotates anticlockwise (see fig. 2), so as to drive the disconnecting switch driving gear (15), and then drive the disconnecting switch driven gear (16) to rotate clockwise, so as to drive the disconnecting switch operation shaft (17) to rotate clockwise.

Energy storage process of closing energy storage release and closing process of switch

a. The spring operating mechanism drives the switch to be switched on from the energy storage of a switch switching-on energy storage tension spring (in a pre-stretching state) (11) to the energy release of the spring, the switch energy storage shaft (48) rotates 360 degrees in total, the front 180 degrees are tension energy storage stages of the tension spring, the rear 180 degrees are energy release acting stages, and the cam (47) impacts a switching-on roller (107) to drive the switch to be switched on in place (see fig. 10 and 11).

b. As shown in fig. 4, the switch is in an open state, the disconnecting switch is in a closed state, the open energy storage release (8) is in an energy storage state, the close energy storage release (65) is in a release state, and the switch close energy storage tension spring (pre-stretching state) (11) is in an energy non-storage state (see fig. 8). When the switch is switched on according to the interlocking requirement, the isolating switch is required to be switched on first and then the switch is switched on, and the state allows the switch to be switched on. Referring to fig. 5, in this state, the switch interlock lever (96) is rotated clockwise, freeing the switch interlock pin (98), allowing the closing half shaft (62) to rotate clockwise, closing the switch. If the disconnector is opened as shown in fig. 16, the switch can no longer be closed.

c. Firstly, an energy storage motor (or manual energy storage) drives a cam (47) to rotate clockwise (see fig. 4 and 6) through parts such as a gear (46), after the cam (47) is contacted with a driving roller (101) on a closing energy storage lever (69), the closing energy storage lever (69) is driven to rotate clockwise around a closing lever shaft (60), the driving roller (71) drives a closing energy storage driving plate spring (in a compression state) (99) under the driving of the closing energy storage lever (69), and then drives a closing energy storage tripper pressing plate (66) through a closing energy storage shaft (68) to compress a closing energy storage tripper (in a release state) (65) to an energy storage position (in a closing energy storage tripper (in an energy storage state) (100)). In order to ensure reliable energy storage, a certain overshoot is required when the energy storage is compressed, and the closing energy storage driving plate spring (in a compressed state) (99) absorbs the overshoot through deformation.

d. After the energy storage of the closing energy storage release (in a compressed state) (100) is finished, the cam (47) continues to rotate in the same direction, referring to fig. 7, until the switch closing energy storage tension spring (in a pre-stretched state) (11) automatically rotates forwards after passing through the middle, the energy storage keeping roller (102) is blocked by the closing buckle plate (61) and cannot rotate anticlockwise any more, the driving claw (104) can automatically separate from the driving wheel (103), the switch energy storage motor (2) can not drive the cam (47) to rotate any more, and meanwhile, the switch closing energy storage in-place microswitch (19) also acts to cut off the power supply of the switch energy storage motor (2), so that the closing energy storage is finished (referring to fig. 8).

e. When the closing energy storage release (energy storage state) (100) is powered on, the armature (110) pops up, referring to fig. 9, the armature (110) strikes the releasing plate (63) of the closing energy storage release to drive the closing half shaft (62) to rotate anticlockwise, the closing buckle plate (61) is not blocked to rotate any more, and the closing buckle plate (61) can also rotate anticlockwise around the closing buckle plate shaft (58) under the pressure action of the energy storage retaining roller (102).

f. Referring to fig. 10, the cam (47) and other components rotate clockwise around the switch energy storage shaft (48) under the driving of the switch closing energy storage tension spring (in a stretching state) (105), and the cam (47) impacts the closing roller (107) and drives the switch output shaft (4) to rotate counterclockwise through the closing crank arm (106).

h. Referring to fig. 11, after the cam (47) is disengaged from the closing roller (107), the switch output shaft (4) rotates clockwise under the action of the opening pressure spring (86), but the closing holding roller (52) is blocked by the closing holding detent (53) and cannot return, and is kept at the closing position.

k. Referring to fig. 12, in the switching-on process of the switch, the linkage connecting lever (83) rotates anticlockwise to drive the opening energy storage lever (80) to rotate clockwise around the opening lever shaft (81), the pressing shaft (79) no longer presses the opening energy storage driving plate spring (compression state) (78), and the opening energy storage driving plate spring (free state) (108) is recovered, referring to fig. 11, the opening energy storage release pressing plate (9) also returns to the position where the opening energy storage release (energy storage state) (8) is no longer pressed, and the armature (110) is allowed to release again.

And the whole closing power transmission process is finished.

4. Opening process of switch and isolating switch

Firstly, the action process of the brake-separating energy-storing release (energy-storing state) (8) and the brake-separating process of the switch

Referring to fig. 13, after the opening energy storage release (energy storage state) (8) is powered on, the armature (110) pops up (becomes the opening energy storage release (release state) (109)), strikes the opening energy storage release trip plate (7), drives the opening half shaft (6) to rotate clockwise, the opening trip plate (55) is not blocked and rotates clockwise around the trip plate shaft (5), and the release switch output shaft (4) rotates clockwise under the action of the opening pressure spring (86) and the like, so that opening is completed, see fig. 14.

Second energy storage process of brake-separating energy-storage release

Referring to fig. 16, in the process of opening the switch output shaft (4) (clockwise rotation), the linkage connecting lever (83) is driven to rotate clockwise, the opening energy storage lever (80) is driven to rotate anticlockwise around the opening lever shaft (81), the pressing shaft (79) presses the opening energy storage driving plate spring (in a compressed state) (78), referring to fig. 14, the opening energy storage release pressing plate (9) presses the opening energy storage release (in an energy storage state) (8) (referring to fig. 15), and the armature (110) is not allowed to release and pop up any more.

Opening process of isolating switch

The isolating switch only allows the switch to be opened after the switch is opened. Referring to fig. 12, in the process of opening the switch, the isolation associated lock rod (91) is driven by the interlocking connecting piece (84) to rotate clockwise around the interlocking rod shaft (92) until the opening is in place (see fig. 16), and the isolation switch interlocking rod (91) no longer blocks the clockwise rotation of the isolation switch interlocking connecting lever (93), namely the isolation switch is allowed to open.

Referring to fig. 2, the manual operation disconnecting switch operating handle (18) rotates anticlockwise (driven by a gear during electric operation), drives the disconnecting switch operating shaft (17) to rotate anticlockwise, and the disconnecting switch operating spring (74) passes through the middle and the back (see fig. 15), and in turn drives the disconnecting switch linkage connecting lever (72) to drive the disconnecting switch operating shaft (17) to rotate clockwise until the disconnecting switch driving connecting shaft (32) is limited by the arc-shaped limiting grooves on the front plate (12) and the back plate (13). In addition, when the disconnecting switch operating shaft (17) rotates, the disconnecting switch driven gear (16) and the disconnecting switch driving gear (15) can be driven to rotate simultaneously, and the disconnecting switch operating motor (14) can also be driven to rotate through the disconnecting switch operating motor output shaft (31).

5. Interlocking relationship between switches and isolating switches

The following interlocking relation exists between the switch and the isolating switch on the mechanical aspect: when the switch is switched on, the isolating switch must be switched on in place first, and then the switch can be switched on again; when the switch is opened, the switch must be opened in place and then separated from the switch, otherwise, the switch cannot be operated.
