Problems solved by technology
Facing the regular inspection work of the electrical control system containing a large number of relays, the technicians not only have a high intensity of repetitive work, low calibration efficiency, and are prone to fatigue, but also judge whether the calibration data meets the technical requirements, which is mainly determined by the calibration personnel themselves , strong subjectivity, which is not conducive to standardized maintenance of equipment
[0007] 2. Calibration tools are relatively backward. Since the external AC and DC power supplies need to be connected to the coil end of the relay with short wires manually during the calibration, there is a potential safety hazard for technicians to get an electric shock during the calibration
[0008] 3. The traditional calibration method can only measure some electrical parameters of the relay, such as coil resistance, normally open contact resistance, normally closed contact resistance
However, important relay parameters such as pull-in voltage, release voltage, and action time cannot be measured
[0009] 4. The verification data is not effectively saved and classified

The invention relates to the technical field of detection and maintenance of secondary equipment of power systems, and specifically relates to test equipment and a test method for a secondary circuit relay of an energy storage unit. The test equipment for the secondary circuit relay of the energy storage unit comprises a relay test pedestal, a relay electrical parameter test device, a health state intelligent analysis device and a man-machine interaction device, wherein the relay electrical parameter test device is separately connected with the relay test pedestal and the health state intelligent analysis device; and the man-machine interaction device is separately connected with the health state intelligent analysis device and the relay electrical parameter test device. The test equipment is simple in structure and reasonable in design, reduces the labor intensity of technicians in a relay regular checking process to a great extent, and improves the accuracy and standardization of relay verification.
Description
technical field [0001] The invention relates to the technical field of detection and maintenance of secondary equipment in a power system, and more specifically, to a method for testing a secondary circuit relay of an energy storage unit. Background technique [0002] At present, there is no automatic calibration device that can be applied to the MTI relay in the secondary circuit of the control system of the Guangzhou Energy Storage Hydropower Plant. The method is generally a completely manual method, that is, one person directly connects the power supply to the coil end of the relay with a short wire to force the relay to energize, and then the other person uses a multimeter to directly measure the resistance of the normally open contact of the relay. After obtaining the resistance data, measure That's it. [0003] In the secondary circuits of power systems and other electrical control systems, various types of relays are often used in occasions that require state monitor...
