Description

Operation handle for ring main unit {OPERATING HANDLE FOR RMU}

The present invention relates to an operation handle for a ring main unit, and more particularly, to an operation handle for a ring main unit that can prevent a shock generated when a mechanism inside a unit is operated, thereby ensuring durability of the mechanism.

Normally, the ring main unit (RMU) is a facility used for surveillance, control, and protection of electrical systems used for power distribution to the power supplied from power distribution.

The ring main unit is composed of a circuit breaker, a switch, an aggregate of ground and conductors, and is disposed in a structure sealed by SF6 gas.

Fig. 1 is a perspective view showing a ring main unit in a state where a conventional operation handle is fitted, and Figs. 2a to 2c are perspective views showing an example in which a conventional operation handle is coupled to the mechanism.

Referring to FIGS. 1 and 2A to 2C, a mechanism 2 is provided in a conventional ring main unit body 1. The mechanism 2 can be operated through the operating handle 10

The mechanism (2) for maintaining the 3-position state is opened through the main circuit operation hole (not shown) of the LBS through the ground circuit operation hole (not shown) Can be changed.

Here, in the case of changing from the charged state to the grounded state or from the grounded state to the charged state, the open position must always be passed.

3 is a view showing a state of engagement between a conventional operation handle and a spring of the mechanism.

Referring to FIG. 3, the above-described conventional operation handle 10 is inserted into the main circuit operation hole and the LBS can be operated from the open state to the closing state.

Figs. 4A to 4C are diagrams showing an operation relationship between a conventional operation handle and a spring of a mechanism.

4A to 4C show a state in which the LBS mechanism 2 is operated by the spring 2c when the state is changed using the operation handle 10 from the open state to the closing state.

The configuration number '2a' is the first rotation, and '2b' is the second rotation. The center of the second rotating body 2b can be engaged with the manipulating handle 10.

When the operator rotates the operation handle 10 in the clockwise direction, the spring 2c is gradually compressed by the operation handle rotated in the clockwise direction, and the force is applied to the point (dead point, about 110 degrees) Receive.

At this time, due to the compressive force of the spring 2c, the worker is about 200 to 250 kgf. And is operated by the restoring force of the spring 2c in the state of FIG. 4B to FIG. 4C, that is, at an instant when the point exceeds the dead point.

Here, the point at which the operation is completed is a position rotated about 180 degrees from the initial position.

The same principle applies when changing the state of the LBS mechanism (2) from an open state to an open state or when changing the state of a ground circuit operation hole.

5 is a view showing a conventional operation handle.

4A to 5, the structure of the operation handle as described above will be described.

The conventional operating handle 10 is composed of a handle body 11, a link 12, a pin 13, a washer 14 and a handle 15.

Here, the handle body 11, the link 12, and the pin 13 are formed by welding so as to be integral with each other.

The end of the handle body 11 is inserted into the main circuit operation hole of the LBS mechanism 2 to operate the LBS.

When the LBS mechanism 2 is operated, the mechanism is operated by the restoring elastic force of the spring 2c while the spring 2c is uncompressed when it moves by the force of the operator until it passes over the dead point .

At this time, the operator grasps the handle 10, and a force is applied to the handle 10 to reverse the spring mechanism.

Thus, the compressive force of the spring 2c of the spring mechanism is directly transmitted to the operator's hand, which increases as the handle 10 is not moved in a clockwise direction (in the case of open-> input).

In addition to this, the reaction force is transmitted to the operation hole of the LBS mechanism 2 by the impact transmitted to the operator, so that not only the operation hole but also the interlocking structure constituting the mechanism is impacted by the impact on the mechanism durability There is a problem that it is broken.

FIG. 9 is a view showing a state where the operation handle of the present invention is freely rotated, and FIG. 10 is a view showing a position of the operation handle after the mechanism according to the present invention is completed.

Referring to Figs. 9 and 10, the operation state of the operation handle of the present invention for the mechanism operation will be described.

9, the operating rod 300 according to the present invention is formed at the other end of the handle body 100 in a state of being connected to the roller 200 installed to be rotated in the hollow of the handle body 100, The movable guide hole 101 can be freely rotated.

The manipulating handle 3 of the present invention constructed as described above is connected to the second rotating body 2b of the mechanism 2 via the inflow hole formed in the main body 1 of the ring main unit as shown in Fig. It can enter the center of rotation.

That is, the pin member 120 provided at one end of the handle body 100 can be engaged with the center of rotation of the second rotating body 2b of the mechanism 2. [

At this time, the spring member 2c for elastically connecting the outer circumferences of the first rotating body 2a and the second rotating body 2b of the mechanism 2 is in a relaxed state.

In addition, the operating rod 300 according to the present invention is freely rotatable along the moving guide hole 101 within a range of 180 degrees from one end of the handle body 100.

FIGS. 10A and 10B are diagrams showing the state before the operation rod is rotated, FIGS. 11A and 11B are views showing the state of the operation rod at the moment leading to the dead point of the spring member, FIGS. 12A, And the position of the operation handle at the completion.

10A and 10B, the actuating rod 300 according to the present invention is rotated along the clockwise direction and is brought into close contact with one end of the movement guide hole 101 formed at one end of the handle body 100.

At this time, the rotation angle of the operation rod 300 may be 0 degree.

Here, the operating rod 300 is connected to a roller 200 rotatably arranged in the hollow of the handle body 100 and rotated.

In this state, as shown in Figs. 11A and 11B, the rotation angle of the operation rod 300 can be rotated to reach 110 degrees, reaching the dead point where the spring member 2c is compressed to the maximum.

At this moment, the spring member 2c returns to its original state at the moment when it exceeds the dead point, and a returning elastic force is formed.

12A and 12B, as soon as the rotational angle of the operating rod 300 exceeds the dead point, the spring member 2c is rotated to rotate the second rotating body 2b.

At this time, the operation rod 300 contacts one end of the movement guide hole 201, and there is a margin of a certain angle along the other end side of the movement guide hole 201.

That is, when the spring member 2c is moved beyond the dead point and the spring member 2c is uncompressed, the impact generated as the mechanism 2 is operated by the moving force causes the operation rod 300 to move in the movement guide hole 101, So that an allowance for retracting is ensured and may not be transmitted to the operation rod 300 as it is.

In addition, since the impact on the rotational center of the second rotating body 2b of the mechanism 2 can also be absorbed, there is an advantage that the durability of the mechanism 2 itself can be secured.

13 is a view showing another example of the handle body according to the present invention.

Referring to FIG. 13, the handle body 100 'according to the present invention includes a first handle body 102' coupled to the second rotator 2b of the mechanism 2 (see FIG. 2) And a second handle body 101 'which is detachable from the body 101' and on which the movement guide hole 101 is formed.

That is, the second handle body 101 'according to the present invention can be detached from the first handle body 102' and can be replaceably coupled.

Here, the first and second handle bodies 102 'and 101' may be detachably coupled through hooks.

Of course, the coupling methods of the first and second hook bodies 102 'and 101' may be applied to other methods than the hook coupling as described above.

Therefore, in the present invention, when a plurality of second handle bodies 101 'having different angular ranges between the moving guide holes 101 are provided, one of the plurality of second handle bodies 101' 1 ", it is advantageous that various angular ranges are selected and used.
