Description
Technical field
The invention belongs to electrical equipment and electrical engineering technical field, it is related to one kind from power transmission dress
Put, more particularly, to a kind of omnipotent breaker from power transmission device.
Background technology
At present, in the low-voltage distribution system of 0.4KV, main circuit breaker, such as DW15 type, DW17
The omnipotent breakers such as type all have o-volt protection function, that is, when circuit be less than rated voltage or on
Under level power-off condition, breaker meeting automatic trip, it is to avoid security incident occurs.
Existing omnipotent breaker has a case that o-volt protection function although in fault decompression
Lower meeting automatic trip, efficiently avoid the generation of security incident.But, have a power failure in non-faulting
In decompression tripping operation, or when after trouble shooting, circuit recovers normal, for example, when circuit is extensive
When multiple rated voltage or higher level's incoming call, if again do not pressed switch knob, breaker would not be certainly
Row closes a floodgate it is impossible to realize from power transmission function.So electrician must be needed to go combined floodgate ability to switchgear house
Recover electricity consumption.Like this, first, sometimes higher level has sent a telegram here but electrician is not aware that,
Delay electric power feeding time；Secondth, because an electrician can not possibly only manage a switchgear house, because
Multiple switchgear houses power transmission one by one is needed, workload is very big during this power transmission.For this reason, some users
Do not want to take the trouble, directly the no-voltage release of breaker is removed, but such breaker just loses
O-volt protection function, easily cause the accident generation.
In view of the above-mentioned technological deficiency of prior art, in the urgent need to develop a kind of new can be square
Just the device of the automatic power transmission of omnipotent breaker.
Content of the invention
It is an object of the invention to overcoming shortcoming present in prior art, provide a kind of universal
Breaker from power transmission device, this device omnipotent breaker non-faulting decompression tripping operation after, extensive
Breaker is enabled from power transmission during multiple normal power supply.
To achieve these goals, the present invention provides following technical scheme：A kind of air circuit breaker
Device from power transmission device, it includes first voltage relay, continue in second voltage relay, centre
Electrical equipment, closing relay and the time relay are it is characterised in that breaker enters the three-phase of line side
Sampling power supply is respectively connected in described first voltage relay and the coil of second voltage relay,
The opened point of described first voltage relay and second voltage relay, closing relay normally closed
The normally closed point of point and breaker accesses in the coil of the described time relay after connecting one by one, described
The opened point series connection of the time relay accesses in the coil of described auxiliary reclay, and described combined floodgate continues
It is series at the line of described closing relay after the opened point parallel connection of the opened point of electrical equipment and breaker
In circle, two after the normally closed point series connection of the opened point of described auxiliary reclay and described closing relay
End is parallel on the switch knob of breaker.
Further, wherein, described breaker enters the three-phase sampling power supply of line side respectively by one
Individual automatic switch accesses in described first voltage relay and the coil of second voltage relay.
The small volume from power transmission device of the omnipotent breaker of the present invention, easy-to-connect, can be straight
Connect and be arranged in omnipotent breaker cabinet, can be widely applied to each industrial and mining enterprises, residential area etc..
Meanwhile, accelerating after non-faulting has a power failure from power transmission device of this omnipotent breaker recovers electricity consumption
Speed, greatlys save the labour of powered operation personnel, and solving breaker cannot be from power transmission
Defect.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the content of embodiment is not made
It is the restriction to protection scope of the present invention.
The present invention relates to a kind of omnipotent breaker from power transmission device, this device universal break
After the device non-faulting decompression tripping operation of road, recover to enable breaker from power transmission during normal power supply.
Fig. 1 shows the key wiring diagram from power transmission device of the omnipotent breaker of the present invention.
As shown in figure 1, the omnipotent breaker of the present invention include first voltage relay from power transmission device
Device 1YJ, second voltage relay 2YJ, auxiliary reclay 1ZJ, closing relay 2ZJ and when
Between relay SJ.With reference to Fig. 1, viewed from above understand, wherein：
Breaker enters the three-phase sampling power supply X1 of line side, and X2, X3 are respectively connected to described first electricity
In the coil of potential relay 1YJ and second voltage relay 2YJ.Preferably, described breaker
Enter the three-phase sampling power supply X1 of line side, X2, X3 pass through automatic switch ZK respectively and access institute
State in first voltage relay 1YJ and the coil of second voltage relay 2YJ.
The opened point of described first voltage relay 1YJ, second voltage relay 2YJ normally opened
The normally closed point of point, the normally closed point of closing relay 2ZJ and breaker accesses described after connecting one by one
In the coil of time relay sj.
The opened point series connection of described time relay sj accesses the coil of described auxiliary reclay 1ZJ
In.
It is series at institute after the opened point parallel connection of the opened point of described closing relay 2ZJ and breaker
State in the coil of closing relay 2ZJ.
The opened point of described auxiliary reclay 1ZJ and the normally closed point string of described closing relay 2ZJ
After connection, two ends are parallel on the switch knob HA of breaker.
In employing the circuit from power transmission device of omnipotent breaker of the present invention, work as circuit
When power failure or voltage are abnormal, each components and parts are in the state shown in Fig. 1.Wherein, in described
Between the opened point of relay 1ZJ be in open state, switch knob HA is failure to actuate.
When line voltage distribution is normal, described first voltage relay 1YJ and second voltage relay
The coil of 2YJ obtains electric work, their opened point closure, so that the described time relay
The coil electricity adhesive of SJ, the opened point closure of described time relay sj after time delay, this
When, the coil electricity adhesive of described auxiliary reclay 1ZJ is so that described auxiliary reclay 1ZJ
The switch knob HA being parallel to breaker on opened point closure, thus moment connect open circuit
Device closing circuit is it is achieved that from power transmission function.
Connect due to after the opened point of described closing relay 2ZJ and the opened point parallel connection of breaker
In the coil of described closing relay 2ZJ, the opened point closure of breaker after breaker power transmission
Thus connecting closing relay coil, now, described closing relay 2ZJ be parallel to open circuit
Normally closed point on the switch knob HA of device is changed into opened point, disconnects closing circuit, thus not
Closing coil can be made long charged, also will not cause misdelivery electricity.
The small volume from power transmission device of the omnipotent breaker of the present invention, easy-to-connect, can be straight
Connect and be arranged in omnipotent breaker cabinet, can be widely applied to each industrial and mining enterprises, residential area etc..
Meanwhile, accelerating after non-faulting has a power failure from power transmission device of this omnipotent breaker recovers electricity consumption
Speed, greatlys save the labour of powered operation personnel, and solving breaker cannot be from power transmission
Defect.
