Abstract
The utility model provides an electronic isolator operating device control circuit automatic cutout device, the device connect among electronic isolator operating device self -sustaining return circuit, the electronic operating device self -sustaining return circuit of the isolator overlap joint delay control return circuit of connecting in parallel to cut off auxiliary contact with the delay relay's in delay control return circuit time delay and concatenate the return circuit into self -sustaining, thereby form electronic isolator operating device control circuit automatic cutout device, when control circuit branch / combined floodgate contactor K1K2 actuation, delay relay receives electricity back delay relay time delay in 10 seconds to cut off the auxiliary contact automatic cutout self -sustaining return circuit. The beneficial effects are that delaying isolator electric operating mechanism self -sustaining return circuit increase with delay relay and automatically terminating the function, when the actuation of branch / combined floodgate contactor K1K2, delay relay receives the electricity, and avoiding burning out the motor because of the limit switch S2S3 trouble leads to the self -sustaining return circuit to cut off by oneself in the 10 seconds back automatic cutout self -sustaining return circuits of delaying, avoids refusing when the operation, and the inoperation mistiming is moved.
Description
Technical field
The utility model relates to a kind of electric disconnector operating mechanism control loop automatic disconnecting device.
Background technology
Existing isolator operating mechanism self-holding circuit relies on mechanism's limit switch to cut off contactor loop, realizes the self-sustaining releasing of control loop.Its structure as shown in Figure 1, traditional isolator operating mechanism self-holding circuit relies on mechanism separating brake limit switch S2/ combined floodgate limit switch S3 to cut off contactor loop, realize the self-sustaining releasing of control loop, if switch mechanism movement is not in place when disconnecting switch operation, then separating brake limit switch S2/ combined floodgate limit switch S3 is failure to actuate, cause self-holding circuit to be connected all the time, the unanticipated action of switch may be caused.When disconnecting switch operation, if switch mechanism movement is not in place, then limit switch is failure to actuate, and causes self-holding circuit to be connected all the time, therefore may cause the unanticipated action of limit switch.
Summary of the invention
For the unsteadiness of performance in prior art, the purpose of this utility model is to provide a kind of electric disconnector operating mechanism control loop automatic disconnecting device, isolating switch motor-operating mechanism self-holding circuit is increased time delay and automatically terminates function, when point, after shutting-brake control loop connects a period of time, automatically disconnect self-holding circuit.Avoid the tripping when operating, malfunction during inoperation.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of electric disconnector operating mechanism control loop automatic disconnecting device, this automatic disconnecting device is connected among electric disconnector operating mechanism self-holding circuit, wherein: described isolating switch motor-operating mechanism self-holding circuit parallel connection overlap joint delays time to control loop, and be connected in series the delay cutoff auxiliary contact of the time-delay relay in delays time to control loop into self-holding circuit, thus form electric disconnector operating mechanism control loop automatic disconnecting device; When control loop divide/closing contactor K1/K2 adhesive time, time-delay relay after powered 10 seconds time-delay relay delay cutoff auxiliary contact automatically cut off self-holding circuit.
Effect of the present utility model with time-delay relay, isolating switch motor-operating mechanism self-holding circuit is increased time delay to automatically terminate function, when point/closing contactor K1/K2 adhesive time, time-delay relay is powered, time delay cuts off self-holding circuit in 10 seconds afterwards automatically, avoid because limit switch S2/S3 fault causes self-holding circuit not cut off and motor damage voluntarily, avoid the tripping when operating, malfunction during inoperation.

Embodiment
Electric disconnector operating mechanism control loop automatic disconnecting device structure of the present utility model is illustrated by reference to the accompanying drawings.
As shown in Figure 2, electric disconnector operating mechanism control loop automatic disconnecting device of the present utility model, traditional control loop basis increases time-delay relay KT, realize automatic cutting-off controlling loop diagram 2, time-delay relay KT parallel connection overlap joint self-holding circuit, and time-delay relay delay cutoff auxiliary contact are connected in series into self-holding circuit, when pressing switch knob S5, the powered adhesive of closing contactor K2, time-delay relay KT is powered simultaneously, the limit switch S3 that closes a floodgate after motor M combined floodgate puts in place cuts off self-holding circuit, and separating brake process is identical with combined floodgate.
This automatic disconnecting device is connected among electric disconnector operating mechanism self-holding circuit, described isolating switch motor-operating mechanism self-holding circuit parallel connection overlap joint delays time to control loop, and be connected in series the delay cutoff auxiliary contact of the time-delay relay KT in delays time to control loop into self-holding circuit, thus form electric disconnector operating mechanism control loop automatic disconnecting device.When control loop divide/closing contactor K1/K2 adhesive time, time-delay relay KT after powered 10 seconds time-delay relay KT delay cutoff auxiliary contact automatically cut off self-holding circuit.When limit switch S2/S3 fault causes self-holding circuit not cut off voluntarily, time-delay relay KT is powered, time delay after 10 seconds time-delay relay delay cutoff auxiliary contact automatically cut off self-holding circuit, as electrical principle Fig. 3.
