Abstract

The invention belongs to the technical field of electrical research debugging maintaining, and particularly relates to a moving type relay fully automatic verification device. The device comprises anexternal interface module, a touch control screen, a button control area, an output interface module, a node interface module and a power supply interface; the touch control screen comprises all controlling functions and receives all information feedback of other components, and an operator perform all operations of parameter setting, variable input, starting, stopping and switching on and off when the device is operated; the button control area transmits instructions to the touch control screen and can takes the place of the touch control screen to execute all operations; the output interfacemodule is responsible for outputting direct current voltage or alternate current voltage and can measure the direct resistance of a coil and perform real-time power calculation; the node interface module is responsible for measuring the on and off of a node and measures the resistance and attenuation time of the node. The device has the advantages that problems of low relay verification and measuring operation efficiency, poor safety performance, the failure of evaluating the operating state of the relay and the like.

Description

technical field [0001] The invention belongs to the technical field of electrical R&D, debugging and maintenance, and in particular relates to a mobile relay automatic calibration device. Background technique [0002] The relay is an important electrical component that plays a role in protection and control in the secondary circuit of the power system. It is widely used, especially in the design of nuclear power plants. It adopts a more traditional mode. The number of relays is extremely large, and its operating status is directly related to the safe operation of the equipment. However, for a long time, technicians still use the traditional manual method to test relays and evaluate the operating status of relays, which has many disadvantages. [0003] At present, most of the relay calibration work is carried out by means of a relay protection tester and a multimeter. The relay protection tester is used to input the voltage, and the voltage is manually increased. After the pe...
