Further, described high-pressure pump and control cabinet electrically connect.Control cabinet and high-pressure pump electrically connect the pushing quantity that can control high-pressure pump, to satisfy the water requirement.The quantity of used high-pressure pump is not limited to one or two, and two high-pressure pumps preferably are installed.But two pump isolated operations are for subsequent use each other, also can move simultaneously, and the most direct purpose is to satisfy traffic requirement.
Further, be provided with apopore on the water main of described bus-bar, on this apopore high pressure valve be installed.This high pressure valve externally connects the flushing hydraulic giant.
Preferably, between described check valve and the water inlet pressure-regulating valve is installed.
Preferably, described pressure-regulating valve also is connected with return duct.Water in the water tank flows into bus-bar after the high-pressure pump supercharging, the water in the bus-bar is leaded up to the return line flow recovery tank through pressure-regulating valve, and another road enters energy-storage water pots through the water inlet of energy-storage water pots, and whole device is more safe and reliable in such being arranged so that.
Further, described pressure-regulating valve and control cabinet electrically connect.Control cabinet and pressure-regulating valve electrically connect, and enter the water yield of energy-storage water pots with control.Pressure-regulating valve, high-pressure pump connect with the control cabinet mode of taking to select.
Further, described energy-storage water pots top is provided with inflation inlet.By being filled with stabilizing gas to energy-storage water pots to increase the pressure in the energy-storage water pots.Generally speaking, the tank internal pressure need maintain 2-4MPa.
Preferably, described energy-storage water pots is equipped with air bag, and described air bag has an air-filled pore, described air-filled pore and inflation inlet fit.Being filled with air in the air bag increases pressure in the energy-storage water pots, uses convenient.
Described energy-storage water pots bottom is provided with the cleaning mouth.
Compared with prior art, the present invention passes through to the water precharge in the energy-storage water pots, can be within the very first time extinguish arcs, when dropping under the preset water level, the water level in the energy-storage water pots prescribes a time limit, control cabinet sends instruction makes bus-bar from the moisturizing of trend energy-storage water pots, guaranteed that energy-storage water pots internal pressure water is sufficient, can put out many places electric arc or sustained arc, effectively prevented the flashover fault in the living water washing operation.This equipment safety is reliable, and is energy-conservation, easy and simple to handle, is easy to safeguard, and do not had the noise of flushing device, is conducive to the monitoring monitoring of corona sound and initial arc in the operation process.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of the emergent arc-control device of living water washing of the present invention.
Fig. 2 is the cross-sectional schematic of energy-storage water pots of the present invention.
Fig. 3 is bus-bar scheme of installation of the present invention.
The specific embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1 to Fig. 3.
The described living water washing of the present embodiment arc-control device of meeting an urgent need comprises the energy-storage water pots 1 of pre-pressurizing device, and energy-storage water pots 1 is provided with water inlet 11 and delivery port 12.Water inlet 11 connects the water outlet tube coupling 22 of bus-bar 2, and delivery port connects emergent arc extinguishing hydraulic giant outward.Arc extinguishing institute water is ultra-pure water.
The tank inwall bottom of energy-storage water pots arranges level sensor 15, and this level sensor 15 electrically connects with control cabinet 3.When the water level in the energy-storage water pots drops under the preset water level in limited time, control cabinet sends instruction starts working pump, and by bus-bar to the energy-storage water pots moisturizing.
The energy-storage water pots inwall is equipped with pressure sensor 16, this pressure sensor 16 electrically connects with the Pressure gauge 161 that the energy-storage water pots outer wall is installed, the water inlet 11 of energy-storage water pots is connected with the water outlet tube coupling 22 of bus-bar 2 by check valve 221, be provided with entry tube coupling 21, water outlet tube coupling 22 and four apopores on the water main of bus-bar 2, described entry tube coupling 21 connects high-pressure pump 6, and high-pressure pump 6 electrically connects with control cabinet 3; A high pressure valve 7 is installed on each apopore, and high pressure valve 7 external baths are robbed.
Between check valve 221 and water inlet 11 pressure-regulating valve 4 is installed, pressure-regulating valve 4 connects return duct 5.
Energy-storage water pots 1 top is provided with inflation inlet 14.As preferably, at energy-storage water pots 1 air bag 17 is installed, described air bag 17 has an air-filled pore 171, this air-filled pore 171 and inflation inlet 14 fits.
Energy-storage water pots 1 bottom is provided with cleaning mouth 13.
In the operation, before power equipment is carried out living water washing, the ultra-pure water that has a certain amount of preset pressure in the energy-storage water pots, because before being rinsed the power equipment bone dry starting the arc phenomenon occurs very easily all in the flushing process, wash that main equipment stops in case producing electric arc during this time or during fault, at first can rely on the press water that stores in the energy-storage water pots to put out electric arc, water level descends along with the consumption of the water yield in the energy-storage water pots, when dropping under the preset water level, water level prescribes a time limit, level sensor is passed to control cabinet with signal, the control cabinet control bus, the pressure ultra-pure water is pressed in the energy-storage water pots, when water level in the energy-storage water pots rises to the preset water level higher limit, control cabinet makes bus-bar automatically stop moisturizing, guarantees that the press water in the energy-storage water pots is sufficient, even therefore electric arc or sustained arc occur in many places, also supply pressure ultra-pure water arc extinguishing at any time when water requirement increases, thus safety and the reliability of living water washing operation effectively guaranteed.
Only be preferred embodiment of the present invention below, should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with the claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
