Description
Technical field
The utility model relates to a kind of valve arrangement, is specifically related to a kind of central cabinet grounding openning and dosing bib device.
Background technology
At present, in the use procedure of high-tension switch cabinet, by closing the valve on the earthed switch handle hole, be grounded the locking of switch, to prevent that earthed switch is by charged combined floodgate, and the valve on the earthed switch handle hole is realized opening or closing by mechanical latching and electrical interlock: mechanical latching is when circuit breaker cart is in the service position, circuit breaker cart directly locks valve by mechanical linkage, so that can't moving down, opens at valve, the earthed switch operating grip can not be inserted in the earthed switch handle hole, thereby can't the operational grounding switch, when circuit breaker cart was in test position, handcart was ineffective to the mechanical latching of valve; Electrical interlock refers in the situation of a circuit outage, the electrification display junction closure, the solenoid energising, the magnetic attraction dead bolt that produces makes its releasing to the locking of valve, valve can be depressed the earthed switch handle hole is opened, press down valve and insert the earthed switch operating grip and just can divide closing operation to earthed switch, take off the earthed switch operating grip after, valve moves on automatically under the effect of reset tension spring up and closes.Yet, when switch cubicle is in the line maintenance state, because the service work duration is longer, reach several hours even several days, one time circuit keeps outage for a long time, the electrification display normally opened contact is closed for a long time, make the long-time energising of valve locking solenoid and heating burnout does not accurately arrive test position such as circuit breaker cart, at this moment mechanical latching can't be opened valve, can't carry out the closing operation of earthed switch, can only use emergency release TO lower cabinet door, adopt the mode of artificial hanging earthing conductor to finish line maintenance, so that operating process is complicated, increase the operating time, brought unnecessary trouble and waste of time to the maintainer.
The utility model content
The purpose of this utility model is to provide a kind of central cabinet grounding openning and dosing bib device, and the problem that inspection operation is complicated, waste time and energy is easily burnt, caused in its long-time energising of solenoid that can effectively solve the valve latching electromagnet existence of existing switch cabinet grounding switch hole of described central cabinet grounding openning and dosing bib device.
For achieving the above object, the technical solution of the utility model is a kind of central cabinet grounding openning and dosing bib device of design, comprises cabinet, earthed switch operating axis, Z-shaped interlocking bent plate, limiting plate, latching electromagnet, dead bolt, snap and travel switch; Cabinet is provided with the earthed switch hole, cabinet inside is equipped with the earthed switch operating axis, Z-shaped interlocking bent plate is installed on the cabinet by limiting plate and bolt and can moves up and down, and the lower end of Z-shaped interlocking bent plate is positioned at the cabinet inboard, and the upper end of Z-shaped interlocking bent plate is positioned at the cabinet outside; The solenoid of latching electromagnet is electrically connected by field circuit and power supply, latching electromagnet be furnished with can translation dead bolt, dead bolt is furnished with multiple spring, the vertical portion of Z-shaped interlocking bent plate is arranged with upper lockhole and the lower lockhole that matches with dead bolt, the lower end that is positioned at the Z-shaped interlocking bent plate of cabinet inboard is furnished with travel switch, the upper end contact that after can touching field circuit is disconnected is arranged on the travel switch, and the lower end of Z-shaped interlocking bent plate is pressed on the contact of upper end.
Preferably, described field circuit comprises power supply first utmost point, power supply second utmost point, electrification display normally opened contact and travel switch normally-closed contact.
Preferably, described latching electromagnet is furnished with electromagnet stent.
Preferably, described Z-shaped interlocking bent plate is furnished with back-moving spring.
At first, when the examination and repair for high-pressure switch cubicle, circuit breaker cart is retreated to test position from the service position, circuit dead electricity in the circuit breaker cart, the electrification display normally opened contact is closed, and it is electric that the field circuit conducting gets solenoid, latching electromagnet excitation and adhesive dead bolt, make dead bolt overcome snap elastic force and retract, dead bolt is removed the locking to the lower lockhole of Z-shaped interlocking bent plate, and Z-shaped interlocking bent plate can move down; Then, press valve (being the upper end of Z-shaped interlocking bent plate) down with hand, make it together with Z-shaped interlocking bent plate-work to move down, when the upper end contact of travel switch is touched in Z-shaped interlocking bent plate lower end, the travel switch normally-closed contact disconnects, field circuit disconnects and makes solenoid monkey dead electricity, situation about being burned so long-term energising can not occur the solenoid monkey; At last, magnetic force disappears during the solenoid dead electricity, dead bolt stretches out under the thrust of snap and to inserting in the lockhole, make Z-shaped interlocking bent plate locking, be that valve is by locked, even unclamping the hand valve moves on also can be not automatically and closes, cause the interlocking device between Z-shaped interlocking bent plate and the circuit breaker cart guide track limiting device that circuit breaker cart is locked, when thereby earthed switch is in closing position, misoperation occuring also can not make circuit breaker cart advance to the service position from test position, thereby has guaranteed personal safety.
Advantage of the present utility model and beneficial effect are: a kind of central cabinet grounding openning and dosing bib device is provided, and the problem that inspection operation is complicated, waste time and energy is easily burnt, is caused in its long-time energising of solenoid that can effectively solve the valve latching electromagnet existence of existing switch cabinet grounding switch hole of described central cabinet grounding openning and dosing bib device.And this central cabinet grounding openning and dosing bib apparatus structure is simple, and is reasonable in design, easy to use, has good market popularization value.
