And relay KH, the trip coil L and remote control terminal power supply connection, the input termination of the first diode D1
24V power supplys, the output end of the first diode D1 is connected with the second diode D2 and dropping resistor R parallel circuit, described
Second diode D2, electric capacity C, trip coil L are sequentially connected in series the input circuit to form the relay KH；The relay KH
Output loop be connected with signal control terminal；Further comprise controlling being spaced apart for remote control terminal.
The characteristics of the utility model, also resides in,
The dropping resistor R connects with the 3rd diode D3.
The trip coil L is magnetictrip coil.
The relay KH is electromagnetic relay.
Compared with prior art, the utility model in use, by the first diode D1, the second diode D2, electric capacity C,
Mutual cooperation between trip coil L and relay KH, electric capacity C makes whole electricity equivalent to built-in power during use
Road is more stable, solves the existing anti-deenergizing power assisting device that disappears and is brought because remote control terminal can not control multiple live ends simultaneously
Security against fire potential problem.
Brief description of the drawings
Fig. 1 is that the utility model embodiment provides a kind of circuit theory diagrams for the anti-deenergizing power assisting device that disappears.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
The utility model embodiment 1 provides one kind and disappeared anti-deenergizing power assisting device, as shown in figure 1, it include remote control terminal,
Live end and signal control terminal, live end are provided with multiple and are connected in parallel between remote control terminal and signal control terminal；
Live end include trip coil L, the first diode D1, the second diode D2, dropping resistor R, electric capacity C and after
Electrical equipment KH, the trip coil L and remote control terminal power supply connection, the first diode D1 input termination 24V power supplys, the
One diode D1 output end is connected with the second diode D2 and dropping resistor R parallel circuit, the second diode D2, electric capacity C,
Trip coil L is sequentially connected in series the input circuit to form the relay KH；Relay KH output loop and signal control terminal
Connection, further comprise control remote control terminal 1 is spaced apart 2.
Dropping resistor R connects with the 3rd diode D3, it is ensured that dropping resistor R is stable, prevents from charging during anti-phase work, reduces
Voltage loss.
Trip coil L is magnetictrip coil, and so, magnetictrip cost is low, long lifespan and by environment shadow
Sound is small.
Relay is normally opened relay, and the relay KH is electromagnetic relay, so, with less electric current, relatively low
Voltage goes to control larger current, higher voltage.
Operation principle：The first diode D1 and 24V power supplys are connected first, and electric current is through the first diode D1 and the second diode
D2 charges to electric capacity C, and now trip coil L is idle；After accident occurs, by signal control terminal by relay HK
Access, now the second diode D2, electric capacity C, trip coil L and relay KH form loop, in whole process, electric capacity
C compensate for the long-range pressure drop of 24V power supplys and can not control multiple electrical apparatus releases simultaneously caused by off-capacity equivalent to built-in power
The problem of coil.
Using such scheme, compared with prior art, the utility model in use, passing through the first diode D1, the two or two
Mutual cooperation between pole pipe D2, electric capacity C, trip coil L and relay KH, electric capacity C is equivalent to built-in during use
Power supply, make whole circuit more stable, it is more because remote control terminal can not control simultaneously to solve the existing anti-deenergizing power assisting device that disappears
Individual live end and the security against fire potential problem brought；It may even happen that because tripping coil is because of electric current, undertension, it is impossible to
At once trip action is completed, is powered for a long time, causes the major accident for burning tripping coil and fire-fighting power source special.More have very
Person, spot fire may be triggered.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by scope of the claims.
