Description

Technical Field

[0001] The embodiments of the present disclosure belong to the technical field of power distribution equipment, and specifically relate to a valve electric control cabinet. Background Art

[0002] There are two power supply schemes for existing valve wells and drainage wells. One is to directly supply power to the local electric valves, flow meters, and pressure gauges one-to-one from the superior power point. The other is to supply power from the superior power point to the local valve distribution box, and the local electric valves, flow meters, and pressure gauges are powered by the valve distribution box.

[0003] For the first one-to-one power supply solution, the solenoid valves, flow meters, pressure gauges, etc. that need to be powered in the existing valve wells far away from the power supply point must be powered from the upper-level distribution cabinet. Considering the power supply length of the cable, the cable voltage drop, the motor start-up, and the subsequent inspection and maintenance, there are problems. In particular, when the switch signal of the solenoid valve, the flow signal of the flow meter, and the pressure signal of the pressure gauge need to be uploaded to the DCS background, the control cables must be connected separately. The cable connection is very uneconomical and unreasonable, and the long-distance power supply is not conducive to safe inspection and maintenance. If the cable fails, the cable replacement cycle is long, affecting the normal operation of the equipment.

[0004] For the second solution of setting up the valve distribution box on site, the above-mentioned problems caused by long-distance power supply still exist, and the problems caused by not setting up a wireless transmission module and using control cables to connect back to the DCS background also exist.
