Description

Transformer substation's condenser trouble protection device that opens circuit Technical Field The utility model relates to a transformer substation capacitor fault circuit breaking protection device, and belongs to the technical field of capacitor circuit breaking protection. Background In a transformer substation, a capacitor is usually installed in a high-voltage distribution device area or a low-voltage distribution room, the capacitor is composed of two conductors (polar plates) which are close to each other and an insulating medium in the middle, when the capacitor is connected into a circuit, charges can be accumulated on the polar plates under the action of an electric field to form the electric field, so that electric energy is stored, the process is charging, when a power supply no longer supplies power to the capacitor, the charges on the polar plates of the capacitor can be released through the circuit to form current, the process is discharging, and the capacitor realizes the storage and release of the electric energy through continuous charging and discharging. The prior capacitor shell is in a sealed state, once the capacitor fails, a large amount of heat can be generated, if the capacitor cannot be timely separated from a power grid, the capacitor can be exploded seriously, and therefore, the transformer substation capacitor failure circuit breaking protection device is provided. Disclosure of utility model The utility model aims to solve the technical problem of providing a transformer substation capacitor fault circuit-breaking protection device, which solves the problems that in the prior art, as the inside of a capacitor shell is in a sealed state, once a capacitor breaks down, a large amount of heat can be generated, and if the capacitor cannot be separated from a power grid in time, the capacitor can explode seriously.
