Abstract
The utility model discloses long-range control of an oil switch and electric meter plug-in card power transmission device, which belongs to an accessory device for oil switches in power supply systems. An additional rocker arm is fixed on a releasing clamp of an oil switch; one end of the additional rocker arm is fixedly provided with a drive rod; the lower end of the drive rod is fixedly provided with an anvil iron; an electromagnet is arranged below the anvil iron; a coil is sheathed on the electromagnet. Two joints of the coil are connected with output ends of an electronic module, and simultaneously are connected with a control switch in an operating position through conducting wires. The utility model has the advantages of simple structure, economy and practicability.
Description
The utility model relates to a kind of oil switch Long-distance Control and electric meter plug-in card power transmission device, belongs to the auxiliary equipment of electric power system with oil switch.
At present, power supply department has generally all used money drawing plat to the user, like this, the oil switch of former configuration can not continue to use, need be replaced with sulphur hexafloride circuit breaker or vacuum switch, and use above-mentioned two kinds of switches, then also must provide standby working power to the card table, otherwise, after card table internal memory electric weight uses up power failure, can't send.
The purpose of this utility model is to overcome the deficiencies in the prior art part and a kind of oil switch Long-distance Control and electric meter plug-in card power transmission device is provided, and it has not only realized the Long-distance Control to oil switch, and does not need standby working power, just can send.
The purpose of this utility model is to realize like this, promptly be fixed with additional rocking arm on the card taking off of oil switch, additional rocking arm one end is fixed with drive link, drive link lower end fixing anvil iron, anvil iron below is provided with electromagnet, suit coil on it, two joints of coil are connected with the output of electronic module, are connected with the control switch of operating location by lead simultaneously.Electromagnet and electronic module are installed in the attached case.
Compared with prior art, advantage of the present utility model is:
1, simple in structure, oil switch can continue to use the saving fund;
2, do not need stand-by power supply, just can realize the plug-in card power transmission under the card table electroless state, easy to use;
3, can carry out long-range power operation to oil switch in the job site, time saving and energy saving, convenient and practical.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an installation site of the present utility model schematic diagram;
Fig. 3 is the circuit theory diagrams of electronic module of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is the improvement to oil switch, be fixed with additional rocking arm on the card taking off of oil switch, additional rocking arm one end is fixed with drive link, drive link lower end fixing anvil iron, anvil iron below is provided with electromagnet, suit coil on it, two joints of coil are connected with the output that is arranged on its other electronic module, are connected with the control switch of operating location by lead simultaneously.Electromagnet and electronic module are installed in the attached case.The input of electronic module is connected with power supply, power supply+,-interpolar is parallel with diode D1, voltage-stabiliser tube W1 and capacitor C 2, the base series resistor R1 of triode G1, capacitor C 3 is connected with positive electrode of power, be connected with power supply-utmost point by resistance R 2, collector electrode by resistance R 3 and power supply+utmost point is connected, emitter is by capacitor C 4, resistance R 4 respectively with power supply+,-the utmost point connects, and be connected with the base stage of triode G2 by voltage-stabiliser tube W2, the base stage of triode G2 also by resistance R 5 and power supply+utmost point is connected, the emitter of triode G2 and power supply-utmost point is connected, collector electrode by relay J in parallel and diode D3 and power supply+utmost point is connected, power supply+utmost point also is in series with capacitor C 1 and diode D2, relay J 1 one ends of Ka Biaonei are connected with positive electrode of power, the other end is connected with relay J 2, the output of electronic module of the other end of J2 and power supply-very.
When needs cut off the power supply, press the control switch of operating location, coil electricity, electromagnet pops up, and bump anvil iron by the drive link additional rocking arm of jack-up that makes progress, makes and takes off card and be in a disengaged position, and realizes cutting off the power supply; Can realize that when card table internal memory electric weight uses up automatic trip has a power failure, at this moment,, can send as long as the user plugs new electricity card on the card table.
When the no internal memory electric weight of card table, relay J 1 closure, J2 is a normally closed contact, and coil electricity makes the electromagnet excitation, and as above action realizes cutting off the power supply.After the utility model tripping operation, card table and electronic module all are in non-powered state, and after the electricity card that electricity is arranged was inserted the card table, electronic module was in normal operating conditions, at this moment, relay J 2 transfers open-circuit condition to by closure state, in very short a period of time, though relay J 1 is closed, send trip signal, since the open circuit of J2, the coil no current, and electromagnet is failure to actuate.During this period of time, the electric weight in the electricity card is to be input to card table memory chip fully.After Ka Biaonei had electric weight, J1 changed open-circuit condition over to by closure state, and no working power plug-in card power transmission is finished.At this moment J2 returns to closure state again, and the tripping operation when performing the card table and not having electric weight is prepared.
