The locking device has electric and mechanical functions; the cabinet door cannot be opened under a charged condition; a locking mode is reliable; and a high-voltage accident caused by error operation can be effectively avoided.
Description
Technical field
The utility model relates to the forceful electric power locking device, and is particularly relevant with a kind of high-tension switch cabinet door forceful electric power locking device.
Background technology
In existing distribution technique field, high-voltage board has generally adopted the ring network power supply structure, and it is simple in structure, uses reliable.But high-voltage board work the time has high pressure, and action need is very careful, must determine that cabinet is not charged when maintenance, otherwise can cause serious accident when opening.
Whether existing high-voltage board adopts simple mechanical system to carry out locking substantially, only come the proof box door charged by the electrification display on the cabinet door.Common electrification display only possesses the voltage detecting loop, whether the mode by A, B, C three-phase electrified sensor electrical signal of reaction detects in the high-voltage board charged, if certain is mutually charged, the branch road of the corresponding electrified sensor of conducting then, light corresponding charged indicator light, thereby caution operator high-voltage board is in charged operating state.
Obviously, there is very big potential safety hazard in this scheme, lights as the not to be noted charged indicator light of operator, and perhaps charged indicator light self is owing to reasons such as fault cause lighting, all will cause the operator to have under the electric situation and open by mistake the cabinet door, human casualty accident will take place at high-voltage board.
So at this defective that the high-voltage board door exists, the inventor designs a kind of electric and mechanical electrical control mechanism associating closedown mode that combines, this case produces thus.
The utility model content
The utility model provides a kind of high-tension switch cabinet door forceful electric power locking device, be a kind of electric and mechanical electrical control mechanism associating locking device that combines, under the charged situation of cabinet, carry out forced blocking, can't open the cabinet door, closedown mode is reliable, the human casualty accident of effectively avoiding misoperation to cause.
For achieving the above object, the technical solution adopted in the utility model is:
High-tension switch cabinet door forceful electric power locking device comprises electrification display, electrified sensor, electromagnetic lock; Electrified sensor is connected with electrification display, forms high pressure and detects the loop; Electromagnetic lock is connected with electrification display, forms the forceful electric power locked loop; Electromagnetic lock has solenoid and the shift knob that is connected on the high-voltage detecting circuit, and controls its flexible bearing pin by the solenoid break-make; On the cabinet door, have the plug blades corresponding with the electromagnetic lock bearing pin.
Described electrification display also possesses the locking output contact except possessing conventional detection high-voltage signal function.
Described forceful electric power locked loop front end miniature circuit breaker in parallel, external control power supply is as the working power of forceful electric power locking device.
Described electromagnetic lock coil and shift knob are to be connected on the locking output contact branch road of electrification display.
Described electrification display and electromagnetic lock are installed on the high-tension switch cabinet door.
Described shift knob is installed on the operating grip of electromagnetic lock.
After adopting such scheme, the utility model is pressed with electrification display locking output contact disconnection under the electric situation at height, can cause the solenoid dead electricity, and the electromagnetic lock bearing pin is in release (elongation) state, electromagnetic lock can not break away from plug blades by rotating pin, and the cabinet door can't be opened.Do not have at high pressure under the situation of electricity, electrification display locking output contact closure is pressed shift knob and is promptly made solenoid energising, and the electromagnetic lock bearing pin is in adhesive (contractions) state, but this moment just turn operating grip unlatching cabinet door.
When locked loop did not have operating voltage, electrification display locking output contact disconnected, and no matter whether high pressure is charged, all can't open the cabinet door.Latch contact by electrification display provides barring condition, can truly reflect more that in conjunction with mechanical latching electric situation is arranged in the cabinet.
Description of drawings
Fig. 1 is the circuit diagram of the utility model preferred embodiment;
Fig. 2 is the structural representation of electromagnetic lock bearing pin in the utility model preferred embodiment.
Embodiment
In conjunction with the accompanying drawings, the utility model is described in further details.
High-tension switch cabinet door forceful electric power locking device, its circuit structure are referring to Fig. 1, and (1) electrified sensor CGa～c and electrification display GSN three-phase indicator light A～C constitute high pressure and detect the loop.If certain is mutually charged, then light the indicator light of corresponding cabinet door.(2) from the switch cubicle control loop, introduce power supply point ± KM; working power as the forceful electric power locked loop; protect this loop through miniature circuit breaker DZK, the locking output contact K1 of electrification display GSN successively with shift knob J1, the solenoid J2 of electromagnetic lock DSN series connection, constitute locked loop.
The mechanical structure of electromagnetic lock DSN as shown in Figure 2, wherein (1) physical structure position of shift knob J1 in Fig. 1 is mounted on the handle 5 of electromagnetic lock DSN.(2) electromagnetic lock DSN has a bearing pin that can stretch 3, its operate condition is controlled by solenoid J2, when solenoid J2 dead electricity, bearing pin 3 is in release condition (elongation), inserts in the pin-and-hole 41 of cabinet door bolt sheet 4, thus the locking of realization cabinet door, when solenoid J2 switches on, bearing pin 3 is in attracting state (contraction), extracts from pin-and-hole 41, thus the release of realization cabinet door.
Operation principle of the present utility model is as follows: 1, when the working power operate as normal, if height is pressed with, then electrification display GSN locking output contact K1 is in off-state, no matter whether press shift knob J1 this moment, solenoid J2 all is in power failure state, and bearing pin 3 is in release condition (elongation), inserts in the pin-and-hole 41 of cabinet door bolt sheet 4, the cabinet door can't be opened, thereby realizes the locking of cabinet door.2, when the working power operate as normal, if high pressure does not have, then electrification display GSN locking output contact K1 is in closure state, press shift knob J1 this moment, then solenoid J2 is in "on" position, bearing pin 3 is in attracting state (contraction), extracts from pin-and-hole 41, and promptly rotatable handgrip 5 is realized the release of cabinet door.3, when working power disconnects, no matter whether high pressure is charged, and electrification display GSN locking output contact K1 all is in off-state, can't open the cabinet door.
The design of button J1 is based on the consideration of locked loop reliability.If there is not button J1 to connect into locked loop, also can realize the forceful electric power blocking function in theory, but when barring condition is in the situation of " allowing to open the cabinet door ", solenoid J2 will be in "on" position for a long time, this may cause coil burnout.Therefore shift knob J1 is gone in series connection, can guarantee the coil no power under normal conditions, when needs are opened the cabinet door, press the button, if satisfy above-mentioned barring condition, and then solenoid J2 energising, bearing pin 3 adhesives.
The utility model is applicable to all kinds of 10kV high-tension switch cabinets, when being used to prevent that the cabinet inner high voltage from having electricity, opens by mistake the cabinet door, effectively prevents the generation of high-tension electricity accident.
