Problems solved by technology
[0003] The water column jet pressure of charged water flushing is the key to charged water flushing technology. Too small jet pressure may make the impact force of water column flushing too small and affect the effect of flushing, while excessive jet pressure may make water column flushing less effective. Damage to flushing equipment due to excessive blow force, or waste of flushing water
[0004] At present, most of the control methods for the jet pressure of electrified water flushing use the relay button or the car starting knob operation control method, which has a low degree of automation, complicated operation and low safety.

The invention provides a charged water flushing jet pressure control device and a control method thereof. The charged water flushing jet pressure control device comprises a water pump rotation speed sensor, a pressure sensor and a controller, wherein the water pump rotation speed sensor and the pressure sensor are connected with the controller; the water pump rotation speed sensor is used for detecting the rotation speed of a water pump and transmitting rotation speed data to the controller; the pressure sensor is used for detecting pressure of a water outlet of the charged water flushing water pump and transmitting pressure data to the controller; and the controller is used for controlling the rotation speed of a water pump engine according to a comparison result of a preset pressure set value of the water outlet and the pressure of the water outlet of the pressure sensor and displaying the rotation speed of the water pump engine according to the received rotation speed data. According to the charged water flushing jet pressure control device and the control method thereof, jet pressure of a charged water flushing water column can be accurately controlled according to setting of an operator, the operation is simple and convenient, and the safety of charged water flushing is improved.
Description
technical field [0001] The invention relates to the technical field of charged water flushing, in particular to a charged water flushing jet pressure control device and a control method thereof. Background technique [0002] Charged water flushing is a live working method that uses a high-resistivity pressure water column to clean the outer insulation of power ceramics or glass. It is one of the effective means to prevent pollution flashover accidents in substation equipment. Compared with the traditional power failure cleaning method, the electrical equipment is easy to clean with live water, has high work efficiency and good cleaning effect, which not only reduces power failure, but also achieves the purpose of anti-pollution flashover, and has significant economic benefits. [0003] The water column jet pressure of charged water flushing is the key to charged water flushing technology. Too small jet pressure may make the impact force of water column flushing too small and...
