Abstract

The embodiment of the invention discloses an electrical equipment testing method and device. The method comprises the following steps: controlling the target switch of the to-be-tested electrical equipment to be in a target state, detecting the level of the dry contact corresponding to the target switch by using a testing device; and judging whether the level at the dry contact is matched with a target state or not, if so, determining that the target switch is effective to control the target state, and if not, determining that the target switch is wrong to control wiring of the target state, and / or determining that type selection of the target switch is wrong. According to the method, the local control box and / or the DCS system can be simulated, the electrical equipment to be tested is automatically tested, manual operation of multiple persons is not needed, time and energy consumed for testing the electrical equipment are effectively saved, and the testing efficiency of the electricalequipment is improved.

Description

technical field [0001] The present application relates to the technical field of equipment testing, in particular to an electrical equipment testing method and device. Background technique [0002] In the field of power electronics, the electrical circuit used to monitor, control, regulate and protect the primary equipment is called the secondary circuit, which consists of the secondary winding of the transformer, measuring and monitoring instruments, relays, automatic devices, etc. Connected by control cables, it is specifically used to control, protect, adjust, measure and monitor the working conditions of various parameters and components in the primary circuit. [0003] After the production of electrical equipment is completed, the electrical equipment is usually inspected at the factory. One of the main items that need to be inspected is whether the secondary circuit is working normally. At present, the detection of the secondary circuit of various electrical equipment ...
