[0002] The relay load live test equipment can simulate the load condition of the relay in actual work, ensuring that the relay can work normally when turning on and off the circuit. The equipment usually includes a power supply, a control unit, a load simulation module, and a measurement and display unit. During testing, the equipment applies voltage and current to the relay while monitoring parameters such as action time and contact resistance to evaluate whether the relay's performance meets standard requirements.

[0003] One of the main challenges faced by relay load live test equipment in practical application is its overly complex structural design. Specifically, when each structural component of the equipment is fixedly installed on the mounting plate, the disassembly process becomes extremely tedious and complex once a damaged part needs to be repaired. This complex structural design makes it impossible to quickly replace damaged parts, severely affecting the maintenance efficiency of the equipment.

[0004] In addition, due to the unreasonable structure layout, maintenance personnel will face greater difficulties during maintenance, which not only prolongs the time required for maintenance but also further reduces overall work efficiency. SUMMARY

[0005] The main purpose of the utility model is to provide a relay load live test equipment that can effectively solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0011] In an optional solution of the application, the detection table is fixed on the second modular mounting plate by bolts, the movable frame is fixed on the second modular mounting plate by a support, and the electric push rod is fixed on the support by bolts.
