Machine protection equipment.

The high-voltage circuit breaker is installed in a closed switchgear made of a rectangular metal plate, that is, a cubicle. In the cubicle, an operation mechanism of a circuit breaker, a terminal such as a cable or a bus that is pulled in from the outside, Insulators etc. which support them are also accepted.

Some switchboards are exposed to high voltage conductors or terminals for installing the vacuum circuit breakers or inlet breakers, but the cubicle has a higher safety level for manipulators. It is highly possible to make it easy, and the standardization of cubicle dimensions makes installation planning easy and economical.

On the other hand, the upper part of the high-pressure circuit breaker in the cubicle is a MOC (Mechanism Opreating Cell switch), that is, the cell switch is configured in the housing, the main shaft rod for driving the cell switch is mounted in the vertical direction, the main shaft rod is a circulating circuit breaker It has a structure that interlocks with the internal rotating shaft.

However, while the conventional spindle rod has a standardized length, the bottom height of the cubicle is slightly different depending on the facility, and thus there is a problem in that the interchangeability between components is poor.

In addition, since the main shaft rod does not have its own buffering force, a cell switch failure may occur when an excessively strong impact force is transmitted to the cell switch when the spindle rod is driven up.

The present invention has been proposed to improve the above problems in the prior art, and an object of the present invention is to improve the operation reliability and installation compatibility of the MOC by providing a variable length structure in which a self-damping function of the spindle can be added. have.

A compression spring is formed between the upper rod and the lower rod; A support shaft is formed at an upper end of the lower rod; Characterized in that the insertion groove is formed in the lower end of the upper rod so that the support shaft can be inserted.

In addition, the support shaft is formed in the form of a long hole in which the sliding through hole has a predetermined length in the vertical direction, characterized in that the inner pin is inserted into the sliding through hole in the upper rod is fixedly installed.

In the present invention, the cell switch is within a certain range regardless of the bottom of the cubicle or the installation position of the breaker body because the length of the breaker body can be varied while being cushioned by the compression spring installed at the interruption during the operation of the spindle rod. It can be operated correctly, thereby improving the installation compatibility and maintenance reliability of the device.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to the configuration of the spindle rod according to an embodiment of the present invention through Figures 4 to 6, the spindle rod 30 of the present invention is the lower rod 31 and the upper rod 32 as shown in the exploded view of FIG. The compression spring 34 has a separate structure.

In particular, the support shaft 33 is integrally formed at the upper end of the lower rod 31, and the insertion groove 32a is formed at the lower end of the upper rod 32 corresponding to the upper end of the lower rod 31 so that the coupling can be inserted into each other.

At this time, the coupling interval between the lower rod 31 and the upper rod 32 is supported by the elastic force by the compression spring (34).

In addition, the internal pin 35 is fixedly installed in the insertion groove 32a, and the support shaft 33 is compressed by forming a sliding through hole 33a in which the internal pin 35 can be guided by sliding. The buffer control by the elastic force of the spring 34 was made possible.

It can be seen that the fastening screws 32 'for fastening are formed at the upper end and the lower end of the spindle rod 30, respectively.

Meanwhile, FIG. 1 to FIG. 3 show a schematic configuration of a cubicle 1 in which the spindle rod 30 is to be mounted.

That is, one side of the circuit breaker main body 10 is configured to protrude an energization drive shaft 24 which is rotated in a forward / reverse direction within a predetermined angle range according to the internal energization state, and the lifting lever 20 interlocked with the energization drive shaft 24. As shown in FIG. 3, the pivoting arm 22 is connected by the hinge pin 23 at the lower end, and the pivoting arm 22 is configured to be pivoted together with the energization drive shaft 24.

Then, the guide pin 25 for guiding the up and down flow is inserted into the long hole 21 of the lifting lever 20.

In addition, the upper part of the lifting lever 20 is configured to support the main shaft rod 30 of the present invention so as to be movable in the vertical direction, the lower end of the main shaft rod 30 is supported by the lower support (37) As shown in FIG. 2, the upper end of the main shaft rod 30 has a structure in which the upper end 36 is connected to and supported by the pivoting hole 41, and according to the lifting operation, the cell switch inside the switch housing 40. (Not shown) can be operated.

Since the overall structure of such a cubicle 1 is a known technique, a detailed description thereof will be omitted.

Meanwhile, in the present invention, the support bracket 38 is fixedly installed on the side wall of the cubicle 1 in order to stably support the interruption portion of the spindle rod 30, and the support bracket 38 is disposed in the form of surrounding the spindle rod 30. By constructing the elastic spring 39, the lifting and lowering of the spindle rod 30 was supported by a stable elastic force.

An operation and effect according to the operation of the present invention main shaft rod 30 constituting the above configuration will be described.

As the energization drive shaft 24 is rotated by the energization signal in the circuit breaker main body 10, the lifting lever 20 is driven up and down, and the lifting lever 20 pushes the main shaft rod 30 momentarily. As it is raised, the main shaft rod 30 is interlocked with each other so as to operate the cell switch in the switch housing 40 by pivoting up and down the rotational opening 41.

As the compression spring 34 installed at the load interruption during the ascending operation of the spindle rod 30 of the present invention is temporarily compressed, a buffer switch is performed between the lower rod 31 and the upper rod 32. The impact force transmitted to the can be minimized.

Therefore, even if the main shaft rod 30 of the present invention is installed in a position where the height of the breaker body 10 or the bottom of the cubicle 1 is slightly different, it can be seen that the operation compatibility with the cell switch can be improved. have.

On the other hand, as the lifting lever 20 is moved downward in the original position, the main shaft rod 30 driven to be raised also has the elastic support force by the elastic spring 39 at the lower portion thereof, thereby being returned to the original position to wait for the next operation.
