Embodiment Construction

[0047] Referring to the accompanying drawings, the present invention is described in detail.

[0048] As shown in Figure 2, the control system of the closed circulation pure water cooling device is mainly composed of four parts: power supply and distribution system, sampling and measurement system, controller and man-machine interface.

[0049] Such as image 3 , in the power supply and distribution system, including two main circulation pumps, one for use and one for standby; water supply pump; fan; electric three-way valve; air solenoid valve; electric heater; power switching device, etc.; Power supply incoming line; main circulation pump, supplementary water pump, electric heater are respectively connected with the power switching device.

[0050] The power supply of the control system is designed according to the secondary load. The power supply of the control system is divided into AC power supply and DC control power supply. Both the AC power supply and the DC control po...

Abstract

The invention relates to a thyristor valve group closed cooling water recalculated apparatus control system, which relates to the electricity system and the thyristor valve group cooling apparatus of the electron apparatus. The system is mainly formed by a power distribution system, a sample measuring system, a controller and a human-machine interface. The system adopts dc power couple design to do redundancy design to the CPU and the key instrument and dose temperature control by high, middle and low three sections; it adopts dual node to ascertain the starting logic of the water cooling apparatus, which can to continuous sample to the buffer pot liquid to achieve the leakage preserving of the system; it also adopts electromagnetic compatible design to the system.

Description

technical field [0001] The invention relates to a cooling device for a thyristor valve group in a power system and a power electronic device, in particular to a control system for a closed circulation pure water cooling device for a thyristor valve group. Background technique [0002] With the improvement of people's living standards in our country, more and more household appliances have entered the homes of ordinary people, which has changed my country's power supply and consumption pattern dominated by industrial loads in the past, and the proportion of civilian loads is increasing day by day. . At the same time, the civilian load has changed from the active power consumption dominated by lighting loads in the past to the reactive power consumption dominated by household appliances. The reactive power of the power supply and distribution system has been difficult to meet the needs of users. The reactive power compensation of the power supply and distribution network In ur...
