Description
Technical field
The utility model relates to the electric supply installation technical field connect with automatic reconnection, automatic power transmission device after particularly relating to a kind of power-off.
Background technology
Existing electric supply installation, in use in order to realize under voltage protection function, generally can be added with under-voltage coil, as shown in Figure 1 on lead-in circuit breaker, after power failure, under-voltage coil losing electricity, circuit breaker disconnects, but want the manual power transmission of electrician after incoming call, cause interruption duration to extend; In order to reduce electric work amount, some schemes even eliminate the under-voltage coil of switch, cause line under-voltage unprotect, may burn electric equipment.
Utility model content
Technical problem to be solved in the utility model is automatic power transmission device after being to provide a kind of power-off, described device is by relay K T service time, automatically power on after can realizing power-off, the fault contact of closing circuit series controller, controller is had during fault do not close a floodgate, reduce interruption duration and electric work amount, increase work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: automatic power transmission device after a kind of power-off, described power transmission device comprises circuit breaker Q F, switch knob SB1, opening button SB2 and signal lamp HY, it is characterized in that: described automatic power transmission device also comprises time relay KT and change over switch SA, the power input of described power transmission device is divided into four tunnels, the first via inputs link through described signal lamp HY with the indicator light of described circuit breaker Q F and is connected, second tunnel inputs link with the motor of described circuit breaker Q F and is connected, 3rd tunnel is connected with the under voltage coil input end of described circuit breaker Q F, 4th tunnel is connected with the input of described change over switch SA, first output of described change over switch SA is divided into two-way, the first via connects the closed electromagnetic coil input link of circuit breaker Q F successively after the fault contact of switch knob SB1 and controller, and the second tunnel connects the cutoff solenoid input link of circuit breaker Q F through described opening button SB2, second output of described change over switch SA is divided into two-way, the first via connects the node of the fault contact of switch knob SB1 and controller after the normally opened contact of described time relay KT, and the second tunnel is connecting to neutral line after the normally-closed contact of circuit breaker Q F and the coil of time relay KT successively.
Preferred technical scheme is further: the input of described power transmission device is provided with fuse FU.
The beneficial effect adopting technique scheme to produce is: described power transmission device adds time relay KT and change over switch SA on the basis of original power transmission device, when first output of change over switch SA has electricity, manual power transmission and power-off can be realized, when second output of change over switch SA has electricity, automatic power transmission and power-off can be realized by time relay KT; And the fault contact of closing circuit series controller, controller is had during fault and does not close a floodgate, reduce interruption duration and electric work amount, operating efficiency is provided.
Accompanying drawing explanation

Fig. 2 is the schematic diagram of power transmission device described in the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 2, automatic power transmission device after the utility model discloses a kind of power-off, described power transmission device comprises circuit breaker Q F, switch knob SB1, opening button SB2 and signal lamp HY, and described automatic power transmission device also comprises time relay KT and change over switch SA.The power input of described power transmission device is divided into four tunnels after fuse FU, the first via inputs link through described signal lamp HY with the indicator light of described circuit breaker Q F and is connected, second tunnel inputs link with the motor of described circuit breaker Q F and is connected, 3rd tunnel is connected with the under voltage coil input end of described circuit breaker Q F, and the 4th tunnel is connected with the input of described change over switch SA; First output of described change over switch SA is divided into two-way, the first via connects the closed electromagnetic coil input link of circuit breaker Q F successively after the fault contact of switch knob SB1 and controller, and the second tunnel connects the cutoff solenoid input link of circuit breaker Q F through described opening button SB2; Second output of described change over switch SA is divided into two-way, the first via connects the node of the fault contact of switch knob SB1 and controller after the normally opened contact of described time relay KT, and the second tunnel is connecting to neutral line after the normally-closed contact of circuit breaker Q F and the coil of time relay KT successively.
Manual adjustments change over switch SA, when first output of change over switch SA has electricity, time relay KT does not work, power supply is directly connected with circuit breaker Q F with opening button SB2 by switch knob SB1, manually control switch knob SB1 and opening button SB2, can realize the closed of circuit breaker and disconnect, be now manually power supply.
Manual adjustments change over switch SA, when second output of change over switch SA has electricity, time relay KT works, when the coil of time relay K T obtains electric, its normally opened contact timing closing, the closed electromagnetic coil realizing circuit breaker obtains electric, breaker closing, automatic power; And the fault contact of closing circuit series controller, controller is had during fault and does not close a floodgate, reduce interruption duration and electric work amount, operating efficiency is provided.
