Switchboard using bushing type current transformer applied thereto

Abstract

The present invention relates to a switchboard using a bushing type current transformer applied thereto. The switchboard using a bushing type current transformer applied thereto, according to an embodiment of the present invention, may comprise: a terminal bushing; a switchboard terminal coupled to the terminal bushing; a metering transformer bushing which is installed or released from the front part thereof through a breaker chamber, covers the switchboard terminal, and is inserted into the terminal bushing; and a metering transformer which is fastened to the metering transformer bushing anddisposed on the outer circumference of the metering transformer bushing. The metering transformer includes at least one terminal that faces forward, and the metering transformer bushing may include anopening for exposing the at least one terminal to the front thereof.

Description

technical field [0001] The present invention relates to a switchboard, and more specifically, to a switchboard using a bushing-type converter provided with an instrument converter and a bushing for the instrument converter. Background technique [0002] Generally, a switchboard is a device used to monitor, control, and protect a power system. For the operation or control of power stations and substations, and the operation of motors, circuit breakers, inverters, etc. are housed in the switchboard. Appliances and other electrical equipment. [0003] As mentioned above, among the electrical equipment stored in the switchboard, although the equipment installed on the front can be maintained from the front, for the equipment installed on the back, unless a certain level or more of the rear of the switchboard is secured The maintenance space between the panel and the back wall or enter the inside of the switchboard through the front, otherwise it is difficult to maintain.

AI Technical Summary

Problems solved by technology

[0029] According to the above-mentioned structure, the switchboard of the prior art exists, and even if the circuit breaker is removed, the instrument converter 40', more specifically, the terminal 40a of the instrument converter 40' will be covered by the instrument converter. The problem that the tube 31' is blocked and cannot be exposed forward

Furthermore, when confirming and inspecting the instrument converter 40', it is inconvenient to dismantle the instrument converter bushing 31' and reassemble it.

[0030] In addition, since it is necessary to separately assemble the instrument transformer bushing 31' and the instrument transformer 40', it is inconvenient to assemble and the time required for assembly is relatively long. The length in the direction is relatively long, so there is a problem that the length in the front and rear directions of the whole switchboard becomes long
