Description
Technical field
The utility model relates to the anti-lockset of a kind of switch cubicle five.
Background technology
At present, high-tension switch cabinet generally uses electromagnetic lock to carry out charged protection to door of switch cabinet, can not be opened there being the situation lower cabinet door of high-tension electricity.The power supply of electromagnetic lock takes from high voltage potential transformer, if high voltage potential transformer fuse blows or voltage transformer incoming end high voltage source phase shortage, power down is lost safeguard function by electromagnetic lock, certainly will form great threat to the personal safety of operating personnel.Therefore there is very large defect at present in this scheme, how to ensure that in phase shortage situation, also can pin cabinet door safely and effectively just seems particularly important.
Summary of the invention
Goal of the invention of the present utility model is to overcome prior art above shortcomings, and provides a kind of safe and reliable, easy to use, anti-lockset of switch cubicle five with sound and light of alarm.
The technical solution of the utility model is: comprise high pressure sensor, the high-voltage charge display device be connected with high pressure sensor, the locking controller be connected with high-voltage charge display device, is loaded on door of switch cabinet for the electromagnetic lock according to locking controller output control signal On/Off cabinet door, for exporting according to locking controller the audible-visual annunciator that control signal carries out phase shortage warning; Described electromagnetic lock, audible-visual annunciator are connected with locking controller respectively; Described locking controller comprises variable resistor, the optocoupler be connected with variable resistor, is connected to the switch triode of optocoupler output, is serially connected with relay between switch triode collector electrode and power supply terminal (positive polarity); Also comprising is in parallel with relay prevents the diode of over-voltage breakdown switch triode.Diode is used for voltage clamping, prevents over-voltage breakdown switch triode.
Described high-voltage charge display device input is connected with the input of locking controller.
Described high-voltage charge display device input is connected with the variable resistor of locking controller.
Described locking controller output is connected with electromagnetic lock, audible-visual annunciator through the normally-open normally-close contact of relay respectively.
Described high pressure sensor is three, is connected respectively with three phase mains; Described high-voltage charge display device is three, is connected respectively with high pressure sensor; Described locking controller is three, and the output of each locking controller is connected with electromagnetic lock, audible-visual annunciator respectively.
Locking controller input is connected with electrification display input, for receiving high-voltage signal.As long as any phase live locking controller of high-pressure side will export control power supply to electromagnetic lock, be in live locking state all the time for keeping electromagnetic lock.As long as any phase disappearance locking controller of high-pressure side will export control power supply and send sound and light alarm signal for notifying relevant staff to take corresponding counter-measure to audible-visual annunciator.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
In Fig. 1, the utility model comprise be loaded on high-voltage switch cabinet door for close locker door electromagnetic lock 2, export the signal of telecommunication for receiving high-voltage charge display device 1 and export control signal to the locking controller 3 of electromagnetic lock and acousto-optic alarm reminder, for carrying out the sound and light alarm prompting device 4 of phase shortage warning.The input of locking controller 3 is connected with high-voltage charge display device 1 input, and locking controller 3 one road output is connected with electromagnetic lock 2, and another road output is connected with audible-visual annunciator 4.High pressure sensor 5 is connected with high-voltage charge display device 1.The input of high-voltage charge display device 1 and output are in fact same group of terminal, i.e. a, b, c terminal, namely as the input of high-voltage charge display device 1 simultaneously also as output.
In high-tension switch cabinet, when switch cubicle high tension loop is charged, the three-phase voltage signal of locking controller input after high pressure sensor and high-voltage charge display device dividing potential drop, this three-phase voltage signal is through variable resistor R1, R2, R3 provides the operating current of several milliamperes respectively to optocoupler, make optocoupler output services, 6V voltage is through optocoupler output and R5, R4 dividing potential drop provides operating current to switch triode Q1 base stage b, make switch triode Q1 conducting (Q2, Q3 conducting principle is identical), 6V voltage produces relay operating current through the collector electrode c of relay coil and switch triode and emitter e, make relay J 1, J2, the charged adhesive of J3, direct current 6V power supply is powered to electromagnetic lock closing coil through relay normally open contact simultaneously, make electromagnetic lock live locking, high-voltage cabinet door can not be opened.
Power to electromagnetic lock respectively by three tunnel relay J 1, the parallel connection of J2, J3 normally opened contact owing to being three-phase high-voltage signal, therefore three-phase high-voltage lacks any phase time and can ensure electromagnetic lock live locking, plays the situation preventing from opening by mistake cabinet door because of phase shortage and occurs.
When any phase high pressure disappearance, corresponding input voltage is zero, optocoupler dead electricity disconnects, switch triode ends, make corresponding relay electric-loss, direct current 6V power supply is powered to audible-visual annunciator through its relay normally-closed contact, and audible-visual annunciator sends sound and light alarm signal and reminds relevant staff's switch cubicle to be in non-full-phase state.So that it takes corresponding counter-measure.
