Abstract
The present invention relates to relay control fields, and in particular to a kind of anti-jump one-way conduction control circuit of low pressure.The present invention has found by accident analysis, due to that can generate reverse current in separating brake making process；Simultaneously because the time difference caused by the adhesion of relay can make anti-jump loop that can not play a role.Therefore, the present invention in closing circuit by being arranged one way conducting device, so that will not generate backward current in closing circuit before anti-jump loop connection, breaker is avoided frequently to suit.The present invention has practicability, reliability and stability, and structure is simple, is easy installation.
Description
Technical field
The present invention relates to relay control fields, and in particular to a kind of anti-jump one-way conduction control circuit of low pressure.
Background technique
Anti-trip relay is widely used in low-tension switch cabinet, and is used in power plant, real estate and industrial and mining enterprises.It opens
Closing operation itself, there are the limitations of certain operation circulation to require, the performance requirements of the arc-chutes mainly switched it is certain go to swim
From the time.When switch operation, if combined floodgate meets failure or has trip signal, it will lead to switch while receiving combined floodgate and tripping life
It enables, switch is made to repeat the actuation cycle closed a floodgate, tripped, finally result in switch explosion, although design anti-jump loop prevents from tripping,
Still the failure for repeating to close a floodgate can occur.
Summary of the invention
The object of the present invention is to provide a kind of anti-jump one-way conduction control circuits of low pressure, ask to solve to repeat to close a floodgate
Topic.
To achieve the above object, the present invention improves a kind of anti-jump one-way conduction control circuit of low pressure, including closing circuit,
The normally closed of control switch, the normally-closed contact of anti-trip relay, closing coil and opening coil is in series in the closing circuit
Contact is in series with one way conducting device in the closing circuit.
Further, the control switch, the normally-closed contact of anti-trip relay, closing coil and opening coil is normally closed
Contact is sequentially connected in series.
Further, the one way conducting device is diode.
Further, it is also in series on the spot/remote control in the closing circuit and switches switch.
Further, the closing circuit is parallel with combined floodgate instruction circuit.
The beneficial effects of the present invention are: being found by accident analysis, since reversed electricity can be generated in separating brake making process
Stream；Simultaneously because the time difference caused by the adhesion of relay can make anti-jump loop that can not play a role.Therefore, the present invention passes through
One way conducting device is set in closing circuit, so that backward current will not be generated in closing circuit before anti-jump loop connection,
Breaker is avoided frequently to suit.The present invention has practicability, reliability and stability, and structure is simple, is easy installation.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of the anti-jump one-way conduction secondary control circuit of low pressure of the present invention.
Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawing.
As shown in Figure 1, low-voltage circuit breaker is in band TWJ (tripping position relay), TBJ (tripping guard relay) and HWJ
In the case where (closing operation position relay), when breaker control switch CK and KK close a floodgate, electric current is by the closing point of TBJ, and two
Pole pipe forward conduction is to closing coil Y1, and the normally opened contact S3 of closing coil Y1 is closed, to start anti-jump loop.
QF indicates that breaker, TWJ indicate to jump position supervisory relay in Fig. 1, and HWJ indicates that coincidence supervisory relay, TBJ indicate
Anti-trip relay, QF1 indicate that air switch, CK are that on the spot/far control change-over switch, KK is separating brake/combined floodgate change-over switch, and HR is to close
Lock indicator light, HG are separating brake indicator light.
KK control switch close a floodgate when, electric current from CK followed by KK, TBJ normally-closed contact, diode, closing coil Y1 and
The normally-closed contact S1 of opening coil, closing circuit conducting.
Under normal circumstances, if in-place closing, the normally opened contact S3 of closing coil is closed, so that TBJ coil is powered, TBJ
Coil and the normally opened contact composition of itself are self-locking, while the normally-closed contact of TBJ disconnects, closing circuit power loss.Under abnormal conditions, close
Reverse current is generated in lock circuit, at this time the also not operating closure of S3, TBJ coil is not powered and disconnects its normally-closed contact, then such as
Fruit does not have diode, and the reverse current generated in closing circuit will flow back.And the setting of diode can be played and reversely cannot
The effect of conducting avoids the generation of reverse current in closing circuit.
The present invention realizes the complete separating brake of control loop using the principle of diode, and this control circuit design is simple, practical,
It is easy installation, it is applied widely, meet safe operation, reliable, practical, save the cost requirement.
Specific embodiment of the present invention is presented above, but the present invention is not limited to described embodiment,
The equivalent transformation that diode or one way conducting device position are replaced for example, by using other one way conducting devices, forms in this way
Technical solution is to be finely adjusted to be formed to above-described embodiment, and this technical solution is still fallen in protection scope of the present invention.
