Description

A kind of energy storage arc-control device
Technical field
The utility model relates to a kind of arc-control device, especially is directed against a kind of energy storage arc-control device of the Living water washing operation of power equipment.
Background technology
Along with The development in society and economy, the expansion of electrical network, the electric utility in the electrical network is more and more, and is also more and more by the accident that environmental pollution causes the charging equipment pollution flashover to have a power failure, and brought significant threat for the safe and stable operation of electrical network.For reducing this type of accident, must regularly or according to state remove contamination to power equipment.Living water washing is one of at present best cleaning method, but in the Living water washing operation process, before the equipment bone dry after beginning to accomplish to flushing from flushing, all very easily produces starting the arc phenomenon, even flashover, thus the safety that jeopardizes equipment and operating personnel.Therefore; The electric power enterprise that generally carries out the Living water washing operation requires to be equipped with stand-by pump and prepares against arc extinguishing usefulness when washing master-failure; But stand-by pump forms the readiness time that water jets under high pressure stable, that do not disperse need be certain from starting in the arc extinguishing hydraulic giant; This startup lags behind or the problem of time-delay causes it it to be put out fast in the very first time that electric arc forms, and the development of electric arc is extremely rapidly, tends in readiness time, just develop into flashover fault.The patent No. is that 201020551912.5 " a kind of emergent energy storage device " is though can put out little electric arc of initial stage; But the described energy storage water pot of this patent internal volume is limited; Can only store a certain amount of press water; Therefore when many places generation electric arc or sustained arc occurring, the not enough problem of press water reserves can appear.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of safe and reliable, rapidly and can continue the emergent arc-control device of arc extinguishing.
For realizing above-mentioned technical purpose; The scheme that the utility model provides is: a kind of energy storage arc-control device, comprise the energy storage water pot of precharge device, and the energy storage water pot is provided with water inlet and delivery port; Wherein, The energy storage water pot is provided with level sensor, and the water inlet of energy storage water pot is connected with the pipeline that is provided with water pump and stretches into buffer tank through check valve, and water pump and level sensor electrically connect with control cabinet respectively.
And the energy storage water pot is provided with pressure sensor, and itself and the outside Pressure gauge of energy storage water pot electrically connect.
And energy storage water pot bottom is provided with the cleaning mouth.
The utility model has the advantages that; Through giving the water precharge in the energy storage canister, can be in the very first time extinguish arcs, when the water level in the energy storage canister drops under the preset water level in limited time; Control cabinet sends instruction makes water pump from the moisturizing of trend energy storage canister; Guaranteed that energy storage canister 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 device is safe and reliable, and is energy-conservation, easy and simple to handle, is easy to safeguard, and do not had the noise of flushing device, helps in the operation process monitoring of corona sound and initial arc and monitors.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the embodiment sketch map of the utility model precharge device.
Wherein, 1, the energy storage water pot, 2, water inlet, 3, delivery port, 4, air-filled pore, 5, cleaning mouthful, 6, buffer tank, 7, pipeline, 8, check valve, 9, water pump, 10, control cabinet, 11, level sensor, 12, pressure sensor, 13, Pressure gauge, 14, air bag.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Present embodiment provides a kind of energy storage arc-control device, and is as shown in Figure 1, comprises the energy storage water pot 1 of precharge device, and the precharge device can be external, also can be built-in.Energy storage water pot 1 is provided with water inlet 2 and delivery port 3; Wherein, Energy storage water pot 1 is provided with level sensor 11, and the water inlet 2 of energy storage water pot 1 is connected with the pipeline 7 that is provided with water pump 9 and stretches into buffer tank 6 through check valve 8, and water pump 9 electrically connects with control cabinet 10 respectively with level sensor 11.
Above-mentioned precharge device can be the built-in air bag 14 in energy storage water pot 1 chamber, and as shown in Figure 2, the air-filled pore 4 of this air bag 14 is opened in the top of energy storage water pot 1.Through giving air bag 14 inflations, reach purpose to the pressurization of the ultra-pure water in the energy storage water pot 1.
Energy storage water pot 1 is provided with pressure sensor 12, and itself and energy storage water pot 1 outside Pressure gauge 13 electrically connect.Can understand the pressure condition in the energy storage water pot 1 from the reading of this Pressure gauge 13.
Energy storage water pot 1 bottom is provided with cleaning mouth 5.
In the operation, before power equipment is carried out Living water washing, there is the ultra-pure water of a certain amount of preset pressure in the energy storage water pot 1; Because in the flushing process until before being rinsed the power equipment bone dry starting the arc phenomenon takes place very easily all, during wash that main equipment stops in case producing electric arc or during fault, at first can rely on the press water that stores in the energy storage water pot 1 to put out electric arc; Water level descends along with the consumption of the water yield in the energy storage water pot 1, prescribes a time limit when water level drops under the preset water level, and level sensor 11 is passed to control cabinet 10 with signal; Control cabinet 10 control water pumps 9; Water pump 9 is pressed into 6 ultra-pure water in the buffer tank in the energy storage water pot 1, and when water level rose to the preset water level higher limit in the energy storage water pot 1, control cabinet 10 made water pump 9 stop moisturizing automatically; Guarantee that the press water in the energy storage water pot 1 is sufficient; Therefore even electric arc or sustained arc take place in many places, also supply pressure ultra-pure water arc extinguishing at any time when water requirement increases, thus effectively guarantee the safety and the reliability of Living water washing operation.
