Embodiment Construction

[0025] The application will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present application.

[0026] The invention adopts the method of simultaneously detecting the valve position of the branch valve and the pressure difference of the branch circuit to judge the operation status of the branch waterway of the valve tower of the converter valve, and output an alarm signal when the valve position is abnormal and the pressure difference of the valve tower is normal, so as to protect the DC transmission converter valve Heating element 1 works normally.

[0027] Such as figure 1 As shown, the differential pressure detection module 3 is used to obtain the differential pressure values ​​of the water inlet branch and the water outlet branch of the cooling medium respectively. The maintenance valve...

Abstract

A converter valve tower branch cooling waterway monitoring device comprises a pressure difference detection module and an execution mechanism, the pressure difference detection module is used for obtaining the pressure difference value of a water inlet branch and a water outlet branch of a cooling medium, and the execution mechanism is used for opening a branch valve of the water inlet branch and a branch valve of the water outlet branch. The method has the beneficial effects that the problem that operation maintenance personnel cannot judge the operation condition of the branch waterway of the valve tower when the converter valve is put into operation is solved, and meanwhile, the problem that a single measured value is easily interfered by the environment is solved.

Description

technical field [0001] The invention belongs to the field of high-voltage direct current transmission converter valve cooling, and more specifically relates to a device and method for monitoring a branch cooling water circuit of a valve tower of a converter valve. Background technique [0002] In related technologies, a single valve cooling system usually cools multiple valve towers in HVDC power transmission projects, and each valve tower is equipped with multiple branch cooling water circuits. When the converter valve is unlocked and running, inspection personnel cannot enter the valve hall and cannot judge the operating conditions of the branch waterway of the valve tower. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the purpose of the present invention is to solve the problem that the inspection personnel cannot judge the operating conditions of the valve tower branch waterway when the diverter valve is put into operation, and...
