Problems solved by technology

[0004] The thyristor valve of the static var compensator has large capacity and high efficiency, but its own power loss is also relatively large, and the heat generation is serious. If it cannot be cooled immediately, it will inevitably be difficult to operate normally

Embodiment Construction

[0047] With reference to the drawings, the present invention will be described in detail.

[0048] Such as figure 2 , The control system of the closed circulating 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 circulating pumps, one for one use and one for backup; make-up pump; fan; electric three-way valve; pneumatic solenoid valve; electric heater; power switching device, etc.; power switching device has two The power supply enters the line; the main circulation pump, the make-up pump, and the electric heater are respectively connected to the power switching device.

[0050] The power supply of the water-cooling device is designed according to the secondary load. The power supply of the water-cooling device is divided into an AC power supply and a DC control power sup...

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 of a thyristor valve group in a power system and a power electronic device, in particular to a control system for a closed circulating pure water cooling device of the thyristor valve group. Background technique [0002] With the gradual improvement of people’s living standards in our country, more and more household appliances have entered the homes of ordinary people, which has changed the pattern of electricity supply and consumption in my country, which was dominated by industrial loads in the past, and the proportion of civilian loads is increasing. . At the same time, the civil load has changed from the former active consumption of lighting load to the reactive consumption of household appliances. The reactive power of the power supply and distribution system has been unable to meet the needs of users, and the power supply and distribution network has reactive power compensation. Urgent need for capacity expan...
