An oil circuit breaker applied to a 10KV distribution line

Abstract

The invention discloses an oil circuit breaker applied to a 10KV distribution line, comprising an oil circuit breaker body and a mounting base. As that slide moves downward by rotating two knobs, theuniversal wheel contacts with the ground, thereby facilitating the movement and the transportation of the whole device, reduce the use difficulty of the device, facilitating the movement of the device, reducing the working difficulty of the operator, and improving the practicability of the product; When there is too much transformer oil in the oil tank, the transformer in the oil tank will enter into the oil storage tank through the oil outlet pipe, thereby preventing the oil level in the oil tank from being too high, thereby preventing the gas released from the oil tank from having enough space to buffer, and effectively preventing the oil tank from exploding and catching fire; Improving the safety of the device; When the oil level in the oil tank is low detected by the oil level controller, the one-way solenoid valve and the oil pump are activated to make the transformer oil in the oil storage tank enter into the oil tank, thereby preventing the oil level in the oil tank from being too low and preventing the formation of explosive gas.

Description

technical field [0001] The invention relates to an oil circuit breaker, in particular to an oil circuit breaker applied to a 10KV power distribution circuit. Background technique [0002] Oil circuit breaker, a switchgear that uses sealed insulating oil as the arc-extinguishing medium for breaking faults. It has two forms: multi-oil circuit breaker and low-oil circuit breaker; it was used in power systems earlier, and the technology has been very mature. , the price is relatively cheap, widely used in power grids of various voltage levels, the oil circuit breaker is used to cut off and connect the power supply, and a high-voltage switchgear that can cut off the current quickly and reliably in the event of a short circuit. The existing oil circuit breakers used on 10KV power distribution lines do not have rollers, so the movement and transfer of the device are more difficult, which increases the difficulty of the operator's work, thus affecting the practicability of the devic...

Problems solved by technology

The existing oil circuit breakers used on 10KV power distribution lines do not have rollers, so the movement and transfer of the device are more difficult, which increases the difficulty of the operator's work, thus affecting the practicability of the device; the existing oil circuit breaker used in 10KV power distribution The oil circuit breaker on the line is prone to the situation that the oil level in the fuel tank is too high or too low, so the probability of accidents in the device is high, and the safety of the device is affected
