Abstract
The utility model relates to a pure water treatment device used in converter valve experiments, comprising a control electric cabinet, a cooling tower, a circulating water pump and a converter valve, wherein the control electric cabinet is connected to a control end of the circulating water pump through a power control cable, the circulating water pump is connected with the cooling tower through a water pipe to form a circulating loop, and the circulating water pump is also connected with the converter valve through a stainless steel pipe. The pure water treatment device is simple in structure, simple and convenient in operation, and large in flow, and can be compatible with the converter valve experiments at various voltage grades. In addition, the pure water treatment device can realize automatic control.
Description
Technical field
The utility model belongs to converter valve experimental technique field, especially a kind of pure water processing unit that is used for the converter valve test.
Background technology
DC converter valve is key equipment in the direct current transportation, and this equipment must must be simulated in test actual operating mode and provide cooling circulating water to converter valve according to the relevant criterion type approval test of insulating before using dropping into electrical network.
The converter valve Insulation Test is a high-end experimental technique, comprises some pilot projects in whole test, for the requirement difference of different pilot project cooling waters.The technical barrier that solves is as follows:
(1) flow is controlled automatically, needs remaining in the range of flow of water circulation system long-term stability in the converter valve test;
(2) multichannel flow Balance Control often needs in test to hang some converter valve, and each converter valve water flowing flow needs identical, but the height and position of each converter valve lifting is different in the actual tests operating mode;
(3) temperature fluctuation control, in the converter valve test special test being arranged is heat run, the converter valve water temperature need be heated to a fixed temperature value when heat run, and be stable at this temperature;
(4) there is gas if water circulates in system's automatic vent function in the loop in pipeline, the flow in whole water route will be unstable, and the cooling effect of circulation valve also can be subjected to very big influence, satisfies the exhaust demand so device must be provided with automatic exhaust device.
(5) system's automatic switching function needs configuration two cover control system, two cover circulating water pumps.System breaks down arbitrarily, can automatically switch to another set of control system control.
In the prior art, also do not have and satisfy the above water treatment facilities that requires at present.Therefore designing a kind of device that can satisfy the converter valve test fully is that those skilled in the art are desired.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of converter valve test to use the pure water processing unit, and this device is not only simple in structure, easy to operate, and can realize automatic control.
The purpose of this utility model solves by the following technical programs:
This converter valve test pure water processing unit, comprise the electric cabinet of control, cooling tower, circulating water pump and converter valve, the electric cabinet of described control is connected to the control end of described circulating water pump by the dynamic Control cable, described circulating water pump connects into circulation circuit by water pipe and described cooling tower, and described circulating water pump also is connected with converter valve by stainless steel tube.
The control end of above-mentioned circulating water pump also is connected to host computer by the control optical cable.
In the above-mentioned control electricity cabinet two cover PLC and frequency converters thereof are installed.
Above-mentioned circulating water pump is two horizontal pumps parallel with one another.
The utility model is simple in structure, and is easy and simple to handle, and this complete equipment flow is big, can compatible each electric pressure converter valve test usefulness, and the utility model can be realized automatic control in addition.
