Abstract

The invention discloses a door opening automatic power-off device of a PT cabinet, and relates to the technical field of electrical equipment safety. The door opening automatic power-off device comprises an electric cabinet box, wherein a lifting cabinet, a PT cabinet body and a metering cabinet are correspondingly arranged in an electric cabinet box from bottom to top, travel switches are fixedlyconnected to the inner side walls of the lifting cabinet, the PT cabinet body and the metering cabinet, the inner wall of the rear end of the metering cabinet is fixedly connected with a controller,and the signal output end of the controller is electrically connected with the travel switches. According to the door opening automatic power-off device of the PT cabinet, the travel switches, the controller and a circuit breaker are arranged, so that the advantages of automatic power-off and high safety are achieved; the travel switches are additionally arranged in the lifting cabinet, the PT cabinet body and the metering cabinet, and when the side door of any electric cabinet is opened, the travel switches are triggered, a signal is fed back to the controller, the signal is intercepted by the controller, and the circuit breaker working normally is controlled to jump, so that the outage safety is guaranteed, and meanwhile, automatic outage is achieved, and the personal safety of operatorsis guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical equipment safety, in particular to an automatic power-off device when the door of a PT cabinet is opened. Background technique [0002] PT is also a voltage transformer. The PT cabinet is also called a voltage transformer cabinet or a bus voltage transformer cabinet. Inside it is a set of voltage transformers, a set of fuses and a set of lightning arresters. The fuses are used to protect the voltage transformers. The voltage transformer is a device that converts high voltage into low voltage in proportion. The arrester plays the role of overvoltage protection. Its role is to provide voltage for measurement, voltage for measuring meters, voltage for protection, and voltage for metering. , to provide the voltage used for the power meter, to provide the operation and control power of related equipment, and to provide the voltage circuit for the comprehensive protection device, such as bus insulati...
