Description
Technical field
The utility model relates to a kind of breaker control circuit, and is particularly a kind of with the electrical control supply unit of UPS AC power as breaker control circuit.
Background technology
In the past, the control power supply in 6kV primary cut-out and 380V low pressure frame circuit breaker loop adopted special direct current system power supply usually.This mainly is because the required switching current of electromagnetic operating mechanism of 6kV primary cut-out was big in the past, nearly hundred peace electric currents, and impulse current is also very high, so require to adopt independent DC power supply reliably, this mode is had relatively high expectations to direct current system, expense is more expensive.At present, the 6kV vacuum circuit-breaker adopts spring operating mechanism, and the divide-shut brake electric current generally is no more than 5A, and the respective impact electric current is very little.But the mode of the sort of employing independent DC power supply power supply does not in the past change.Owing to need an independent cover direct current system, make the electrical system wiring comparatively complicated, fixing one's room up becomes many, and the expense that puts into operation is higher.
Therefore need a kind ofly the power supply reliability can be satisfied, the electrical control supply unit of a kind of breaker control circuit that puts into operation can be saved again.
The utility model content
In view of this, technical problem to be solved in the utility model provides and a kind ofly can satisfy the power supply reliability, can save the electrical control supply unit of a kind of breaker control circuit that puts into operation again, have simplified system, reduce the room, implementation cost is cheap, easy to operate.
The utility model is achieved through the following technical solutions:
The UPS AC power formula breaker control circuit that the utility model provides is characterized in that: comprise UPS ac control power supply and breaker control circuit, described UPS ac control power supply and breaker control circuit are electrically connected and form ac power circuit.
Further, described breaker control circuit comprises the interchange frame circuit breaker, and the coiler part of described interchange frame circuit breaker is attempted by UPS ac control power supply two ends, and the auxiliary contact of described interchange frame circuit breaker and relay is serially connected among the scattered control system DCS.
Further, described breaker control circuit also comprises the interchange indicator light, is connected UPS ac control power supply two ends after described interchange indicator light and the auxiliary contact serial connection that exchanges frame circuit breaker.
The beneficial effects of the utility model are: the utility model adopts the electrical control supply unit of a kind of UPS AC power formula as breaker control circuit, can satisfy the power supply reliability, can save input cost again, advantages such as having simplified system, reduce the room, implementation cost is cheap, easy to operate has been applied in the flue gas desulfur device of power plant.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is a UPS AC power formula breaker control circuit structural representation.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection range of the present utility model.
Fig. 1 is a UPS AC power formula breaker control circuit structural representation, as shown in the figure: the UPS AC power formula breaker control circuit that the utility model provides, comprise UPS ac control power supply and breaker control circuit, described UPS ac control power supply 1 and breaker control circuit 2 are electrically connected and form ac power circuit, and the UPS ac control power supply adopts the AC220V power supply.
Further improvement as the foregoing description, described breaker control circuit comprises the interchange frame circuit breaker, coil 3 parts of described interchange frame circuit breaker are attempted by UPS ac control power supply two ends, and the auxiliary contact 4 of described interchange frame circuit breaker and relay is serially connected among the scattered control system DCS.
As the further improvement of the foregoing description, described breaker control circuit also comprises and exchanges indicator light 5, described interchange indicator light 5 be connected UPS ac control power supply two ends after the auxiliary contact 4 that exchanges frame circuit breaker is connected in series.
Corresponding control element all adopts AC200V, like this, the capacity of UPS has still been kept 40kVA and has not been had change, and as calculated, capacity can meet the demands, not enough as capacity, UPS need be increased one-level, its expense is also low than establishing a cover direct current system separately, has simplified system simultaneously, reduce the room layout, also saved the expense of direct current system.
Leftmost side part is exactly the little bus of power supply among the figure, is in the past to draw from DC220V or DC110V power supply, now changes the power supply of UPS alternating current 220V power supply into.Its right side is divided into a control loop of frame circuit breaker.The function that realizes respectively is that power supply, resultant fault warning, energy storage motor energy storage indication, reclosing command, trip command are closed in little disconnection, a distant place/control is switched on the spot, close a floodgate in the loop, tripping in the loop, closes a floodgate/the trip signal lamp, controls power monitoring, numerical tabular power supply from left to right.
Wherein the electric pressure of Xiang Guan components and parts is AC220V, comprising: circuit-breaker-motor 6, indicator light 5, relay and digital display meter etc.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
