Electronic control system of water pump test board with two kinds of high voltage power supplies of 6 kV and 10 kV

Abstract

The invention provides an electronic control system of a water pump test board with two kinds of high voltage power supplies of 6 kV and 10 kV. The electronic control system comprises a high voltage distribution room, a field test board, a test field electrical operation room and a PLC (Programmable Logic Controller) control cabinet; the high voltage distribution room is internally provided with two mutually independent power supply systems of water pumps of two voltage classes of 6 kV and 10 kV; the test field electrical operation room is internally provided with a 6 kV high voltage ring main unit and a 10 kV high voltage ring main unit; the power supply system of the water pump of the 6 kV voltage class is connected with the 6 kV high voltage ring main unit; the power supply system of the water pump of the 10 kV voltage class is connected with the 10 kV high voltage ring main unit; the 6 kV high voltage ring main unit and the 10 V high voltage ring main unit are connected to the field test board through respective outlet cables; the PLC control cabinet is connected with the power supply systems of the water pumps of the two voltage classes of 6 kV and 10 kV; the test field electrical operation room is provided with a field control station; the field control station is connected with the PLC control cabinet and a central control room. According to the electronic control system of the water pump test board with the two kinds of high voltage power supplies of 6 kV and 10 kV provided by the invention, the power supply systems of different voltage classes operate separately, so that the test of the water pumps of different voltage classes can be realized, and the safety and reliability of the power supply of a test system can be guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of water pump testing, and in particular relates to an electric control system of a water pump test bench with two high-voltage power supplies of 6kV and 10kV. Background technique

[0002] With the widespread use of high-power water pumps in the domestic market, high-power water pumps are usually driven by high-voltage motors. According to the level of power supply voltage in my country, most high-voltage motors on the market use two high-voltage power supplies of 6kV and 10kV. For this reason, the high-power water pump test bench equipped by the water pump manufacturer mainly conducts tests on two high-voltage motors of 6kV and 10kV. Due to the different design conditions of the water pump test benches of various manufacturers, the power and control systems are uneven, and there are potential safety hazards in terms of the safety and reliability of the water pump test power supply and the safety of personn...
