The invention provides a capacitor switching module for a JP cabinet, which comprises a casing, a cover plate, mounting fasteners, a handle, a capacitor mounting plate, a connector, a capacitor and athree-phase intelligent composite switch, wherein the casing is a box piece with one side opened; the cover plate is fixedly connected with the opening side of the casing; each front end of the upperside surface and the lower side surface of the casing is fixedly provided with one mounting fastener; the handle is fixedly arranged on the front side plate of the casing; the capacitor mounting plateis fixedly arranged in the shell and separates the space in the shell into two chambers; the connector is fixedly arranged on the rear side plate of the casing; more than one capacitor is arranged; the capacitor is fixedly arranged on the capacitor mounting plate and located in one chamber of the casing; and the three-phase intelligent composite switch is fixedly arranged on the shell and is located in the other chamber of the casing. Through modular design, maintenance, device replacement and capacity expansion are more convenient, the operation is easier, and the problems of inconvenient mounting, maintenance, capacity expansion and other operations for the capacitor switching part in the existing JP cabinet can be solved.
Description
technical field [0001] The invention relates to the technical field of low-voltage integrated power distribution, in particular to a capacitor switching module for a JP cabinet. Background technique [0002] JP cabinet is a new type of comprehensive control box integrating power distribution, metering, protection, control and reactive power compensation. It is widely used in 400V power distribution side, generally installed on the column, and used in conjunction with transformers. [0003] The electrical equipment of the power system will generate reactive power when it is used. Usually the reactive power is inductive, which will reduce the capacity utilization efficiency of the power supply, and it can be improved by appropriately adding capacitance in the system. Usually, the JP cabinet has a compensation room, and its function is to add capacitance to the system according to the demand, so as to increase the efficiency of the power supply. At present, the capacitors and ...
