Description
Technical field
The invention belongs to electrical equipment and electrical engineering technical fields, are related to a kind of from power transmission device, more particularly to one kind
Omnipotent breaker from power transmission device.
Background technique
Currently, main circuit breaker, such as DW15 type, DW17 type omnipotent breaker all have in the low-voltage distribution system of 0.4KV
There is decompression defencive function, i.e., when circuit is lower than under voltage rating or higher level's power-off condition, breaker meeting automatic trip avoids occurring
Safety accident.
Existing omnipotent breaker has the function of o-volt protection, although meeting automatic trip in the case where failure decompression,
Efficiently avoid the generation of safety accident.But route is after the decompression tripping or trouble shooting in non-faulting power failure
When restoring normal, for example, if do not pressed switch knob again, breaker is just when circuit restores voltage rating or higher level sends a telegram here
It will not voluntarily close a floodgate, cannot achieve from power transmission function.So electrician must be needed to go combined floodgate that could restore electricity consumption to switchgear house.In this way
If, first, sometimes higher level has sent a telegram here but electrician is not aware that, delay electric power feeding time；The second, not due to an electrician
A switchgear house may be only managed, therefore needs multiple switchgear houses power transmission one by one when power transmission, workload is very big.For this purpose, some
User does not want to take the trouble, and directly the no-voltage release of breaker is removed, however breaker so just loses o-volt protection function, pole
Easily cause accident.
In view of the above-mentioned technological deficiency of the prior art, there is an urgent need to develop a kind of novel to facilitate omnipotent breaker
The device of automatic power transmission.
Summary of the invention
It is an object of the invention to overcome disadvantage existing in the prior art, provide a kind of omnipotent breaker from power transmission
Device, the device restore to be able to achieve breaker from power transmission when normal power supply after the tripping of omnipotent breaker non-faulting decompression.
To achieve the goals above, the invention provides the following technical scheme: a kind of omnipotent breaker from power transmission device,
It includes first voltage relay, second voltage relay, intermediate relay, closing relay and the time relay, feature
It is, the three-phase sampling power supply of breaker enter line side is respectively connected to the line of the first voltage relay and second voltage relay
In circle, the opened point of the first voltage relay and second voltage relay, the normally closed point of closing relay and breaker
Normally closed point accesses in the coil of the time relay after connecting one by one, described in the opened point series connection access of the time relay
In the coil of intermediate relay, the combined floodgate is series at after the opened point of the closing relay and the opened point parallel connection of breaker
In the coil of relay, both ends are parallel to after the normally closed point series connection of the opened point of the intermediate relay and the closing relay
On the switch knob of breaker.
Further, wherein the three-phase sampling power supply of the breaker enter line side passes through an automatic switch access respectively
In the coil of the first voltage relay and second voltage relay.
Omnipotent breaker of the invention from the small in size of power transmission device, easy-to-connect can be directly mounted at universal
In breaker cabinet, each industrial and mining enterprises, residential area etc. can be widely applied to.Meanwhile the omnipotent breaker from power transmission device
The speed for restoring electricity consumption after non-faulting has a power failure is accelerated, the labour of powered operation personnel is greatly saved, solves breaker
It can not be from the defect of power transmission.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, and the content of embodiment is not as to guarantor of the invention
Protect the limitation of range.
The present invention relates to a kind of omnipotent breakers from power transmission device, and the device is in omnipotent breaker non-faulting decompression
After tripping, restore to be able to achieve breaker from power transmission when normal power supply.
Fig. 1 shows the key wiring diagram from power transmission device of omnipotent breaker of the invention.As shown in Figure 1, this hair
Bright omnipotent breaker from power transmission device include first voltage relay 1YJ, second voltage relay 2YJ, intermediate relay
Device 1ZJ, closing relay 2ZJ and time relay sj.It is viewed from above to know with reference to Fig. 1, in which:
The three-phase of breaker enter line side samples power supply X1, and X2, X3 are respectively connected to the first voltage relay 1YJ and second
In the coil of voltage relay 2YJ.Preferably, the three-phase of the breaker enter line side samples power supply X1, and X2, X3 pass through one respectively
A automatic switch ZK is accessed in the coil of the first voltage relay 1YJ and second voltage relay 2YJ.
Opened point, the opened point of second voltage relay 2YJ, closing relay 2ZJ of the first voltage relay 1YJ
Normally closed point and breaker normally closed point connect one by one after access in the coil of the time relay sj.
The opened point series connection of the time relay sj accesses in the coil of the intermediate relay 1ZJ.
The closing relay is series at after the opened point of the closing relay 2ZJ and the opened point of breaker are in parallel
In the coil of 2ZJ.
Both ends are parallel to after the series connection of the normally closed point of the opened point of the intermediate relay 1ZJ and the closing relay 2ZJ
On the switch knob HA of breaker.
In the route from power transmission device for having used omnipotent breaker of the invention, when line outage or voltage not just
Chang Shi, each component are in state shown in FIG. 1.Wherein, the opened point of the intermediate relay 1ZJ is in open state, closes a floodgate
Button HA is failure to actuate.
When line voltage distribution is normal, the coil of the first voltage relay 1YJ and second voltage relay 2YJ obtain electrician
Make, their opened point closure is attracted, the time after delay so that the coil of the time relay sj is powered
The opened point of relay SJ is closed, and is attracted at this point, the coil of the intermediate relay 1ZJ is powered, so that the intermediate relay
Opened point closure on the switch knob HA for being parallel to breaker of 1ZJ realizes so that moment connects closing circuit of circuit breaker
From power transmission function.
Due to series connection and the combined floodgate relay after the opened point of the closing relay 2ZJ and the opened point parallel connection of breaker
In the coil of device 2ZJ, the opened point closure of breaker is after breaker power transmission to connect closing relay coil, at this point, described
Normally closed point on the switch knob HA for being parallel to breaker of closing relay 2ZJ becomes opened point, disconnects closing circuit, in this way
Closing coil would not be made long charged, misdelivery electricity will not be caused.
Omnipotent breaker of the invention from the small in size of power transmission device, easy-to-connect can be directly mounted at universal
In breaker cabinet, each industrial and mining enterprises, residential area etc. can be widely applied to.Meanwhile the omnipotent breaker from power transmission device
The speed for restoring electricity consumption after non-faulting has a power failure is accelerated, the labour of powered operation personnel is greatly saved, solves breaker
It can not be from the defect of power transmission.
The above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to the present invention
Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description
Other various forms of variations or variation.Here all embodiments can not be exhaustive.It is all to belong to skill of the invention
The obvious changes or variations that art scheme is extended out are still in the scope of protection of the present invention.
