Abstract
The utility model relates to the technical field of power grid security, in particular to a safe and reliable emergent power-off device. Compared with the prior art, the emergent power-off device comprises a leakage protection switch, a power-off control button and a power-off circuit, wherein the leakage protection switch is serially connected to a power supply circuit, the power-off control button is serially connected to the power-off circuit, one end of the power-off circuit is connected with a phase line of the power supply circuit, and the other end of the power-off circuit is grounded or connected with a zero line of the power supply circuit. The power-off emergency device can adopt a multi-point arrangement, the power supply can be cut off in emergency within the power supply range of the leakage protection switch through the power-off emergency device, thereby avoiding the expansion of the electricity utilization accidents, guaranteeing the electricity utilization security, and having good market prospect.
Description
Technical field
The present invention relates to the power grid security technical field, particularly a kind of safe and reliable emergency-off device.
Background technology
In the low-voltage supply line of three-phase 380V or single-phase 220V; Circuit and electrical appliance break down etc. with at the beginning of the electrification, should cut off the electricity supply as early as possible, and this is best emergency measure; Particularly take place under the situation of fire alarm; It can reduce the expansion of accident and stretch, and this just needs a kind of urgent breaker device, and the present invention is a kind of device that is used in emergency circumstances needn't operating a switch by hand and cuts off the power supply.
Summary of the invention
For existing defective and problem in the circuit emergency power off in the solution prior art, a kind of safe and reliable emergency-off device is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: emergency-off device of the present invention comprises an earth leakage circuit-breaker and an outage control button and a deenergizing circuit; Earth leakage circuit-breaker is connected on the feeder circuit; The outage control button is connected on the deenergizing circuit; Deenergizing circuit one end is connected with the phase line of feeder circuit, and deenergizing circuit other end ground connection perhaps is connected with the zero line of feeder circuit.
The invention has the beneficial effects as follows: compared with prior art; Emergency-off device of the present invention can be installed in the optional position of lead, and this device can the multiple spot setting, through this emergency-off device; Emergency power off in can the supply district behind leakage switch; Avoid with the expansion of electrification and stretch, ensure the safety of electricity consumption, have good market prospects.
Description of drawings
Below in conjunction with accompanying drawing and embodiment emergency-off device of the present invention is described further.
Fig. 1 is the circuit diagram of the embodiment 1 of emergency-off device of the present invention;
Fig. 2 is the circuit diagram of the embodiment 2 of emergency-off device of the present invention.
Embodiment
As shown in Figure 1; Fig. 1 is embodiments of the invention 1, and in the present embodiment, emergency-off device of the present invention comprises earth leakage circuit-breaker K, outage control button AN and deenergizing circuit; Earth leakage circuit-breaker K is connected on the feeder circuit; Outage control button AN is connected on the deenergizing circuit, should be provided with protective cover on the outage control button AN, in order to avoid misoperation.The deenergizing circuit input is connected with the phase line of feeder circuit, and the deenergizing circuit output head grounding also is provided with leak resistance R on deenergizing circuit; The resistance of this leak resistance R can trigger earth leakage circuit-breaker K tripping operation and is as the criterion to reach; Deenergizing circuit can be installed a plurality of, feeder circuit be short-circuited or other when use electrification, can press the control button AN that cuts off the power supply nearby; Deenergizing circuit is connected; Earth leakage circuit-breaker K is outage automatically after sensing the electric leakage situation, avoids the expansion with electrification, ensures Electrical Safety.
As shown in Figure 2, Fig. 2 is embodiments of the invention 2, in the present embodiment; Emergency-off device of the present invention also is to comprise earth leakage circuit-breaker K, outage control button AN and deenergizing circuit, on deenergizing circuit, also is provided with leak resistance R, differently with embodiment 1 is; Deenergizing circuit one end is connected with the phase line of feeder circuit, and the deenergizing circuit other end is connected with the zero line of feeder circuit, and is connected in the circuit before the earth leakage circuit-breaker K; Be short-circuited or other is when using electrification at feeder circuit; Can press outage control button AN nearby, deenergizing circuit is connected, and earth leakage circuit-breaker K is outage automatically after sensing the electric leakage situation; Avoid expansion, ensure Electrical Safety with electrification.
Explanation through above-mentioned two embodiment can be known; Emergency-off device of the present invention can be installed in the optional position in the supply district behind the leakage switch, and this device can the multiple spot setting, through this emergency-off device; Emergency power off in can the supply district behind leakage switch; Avoid with the expansion of electrification and stretch, ensure the safety of electricity consumption, have good market prospects.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that and do not breaking away under the situation of the relevant protection range that limits claim that those skilled in the art can make change and/or revise.
