An electric cabinet door fault indicating device and its working method

Abstract

The invention discloses an electrical cabinet door failure indicating device and an operating method thereof, and relates to the field of electrical equipment, in particular to a failure indicating device and an operating method thereof. The invention provides an electrical cabinet door failure indicating device capable of enabling a locked status of a rear cabinet door of a distribution box to be intuitively displayed on a panel and incapable of realizing a switching-on operation in case the rear cabinet door of the distribution box is not firmly locked as well as an operating method of the electrical cabinet door failure indicating device. A pulse generator is fixed in a power distribution cabinet and is in connection with a controller, a pressure sensor is fixed on the rear cabinet door of the power distribution cabinet, is in connection with the controller, and is configured to transmit collected pressure data to the controller, the controller comprises a central processing unit, a memory, a signal transformer and an IO (Input / Output) port, the memory and the IO port are respectively in connection with the central processing unit, and the signal transformer is in connection with the central processing unit by means of the IO port. The electrical cabinet door failure indicating device disclosed by the invention has the advantages of safety, reliability and capability of ensuring human safety and maintaining safety and stability of a power grid.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a fault indicating device and a working method thereof. Background technique [0002] With the development of economy and society, the role of electricity has become more and more prominent, and more and more electricity safety problems have been brought about. Therefore, electric equipment needs to be repaired and maintained regularly. Generally, electric equipment is placed in the distribution box of the substation. The electrical box is designed with double doors and requires two people to operate. One person replaces the device at the front door during maintenance, and one person performs wiring from the rear cabinet door. After the maintenance is completed, the rear cabinet door needs to be closed and locked to ensure that the power distribution is in an insulated state before it can be closed. The normal closing test without knowing the state of the rear cabinet door lead...
