Description

Fixation clamp of bus bar for distributing boards {Fixation clamp of bus bar for distributing board}

The present invention relates to a busbar fixing clamp for switchgear, and more particularly, it is convenient to fix the insulator and the busbar, there is no cross-sectional loss of the busbar, and to prevent foreign substances from entering the fixing clamp connected to the busbar. It relates to a busbar fixed clamp for switchgear.

In general, the switchgear is an electrical installation for safely supplying a relatively high voltage power to the load, and is installed at the base of the substation in a state that is cut off from the outside.

As such, the switchgear panel has a growing demand for electricity, and electrical facilities are becoming more advanced and larger, so the demand for the switchboard is continuously increasing.

The switchgear distributes power supplied from a power company such as KEPCO to perform operation and control of power plants, substations, and electric motors, or plants, buildings, hospitals, APT complexes, and various industrial facilities that require electric power. It is a facility that converts and distributes electric power of special high pressure (special high pressure) supplied from electric power company to low voltage and rated capacity (high or low pressure) suitable for the rating of various equipment and equipment actually used.

Such a switchgear may be formed in various forms and configurations, in which one switchgear independently distributes power supplied from a power company, or a plurality of switchgears including a main switchgear and an auxiliary switchgear are connected to each other and supplied from a power company. Power distribution.

The switchgear is a device in which various units such as a main circuit breaker, an auxiliary circuit breaker and a change device are installed in the casing, and the units are electrically connected to each other. The device is used to switch the power supply on and off at the same time.

Here, the switchboard is provided with a plurality of busbars for distributing power supplied from the outside by electrically connecting the respective units, the busbar is connected to the output terminal of the main circuit breaker, one side bus bus to induce power A busbar and a charity busbar which is connected to the busbar busbar and supply the electric power distributed to the auxiliary bus breaker and the transformer, are provided with a connector for connecting power to the busbar bus to receive power.

However, as many as about 20 epoxy insulators are installed in the busbars in one switchboard, and two fixing holes per one insulator are processed and attached to the busbars, thereby increasing the labor cost and the cross-sectional area of the busbar busbars. Due to the loss of energized current due to the loss, copper busbars having a larger size than the rated capacity should be used, resulting in an increase in manufacturing cost of the switchboard.

In order to solve such a problem, Korean Patent Registration No. 1000804 is a booth for a high-voltage switchgear that connects an epoxy insulator 2 to a bus bar 1 to distribute power supplied to a switchboard to each device provided inside the switchboard.
