Abstract
The utility model discloses an intelligent vacuum contactor and belongs to the field of an electrical control element. The Intelligent vacuum contactor is composed of a current transformer assembly A, an intelligent control circuit board assembly B and a vacuum contactor body C. The intelligent control circuit board assembly B is composed of a rectification circuit unit 1, a remote control circuit unit 2 and a motor comprehensive protection circuit unit 3. The intelligent control circuit board assembly is arranged at an original position that is used for mounting a rectification plate, thereby keeping a structure and a profile mounting size of a conventional vacuum contactor. Intelligent functions of practical remote control and motor comprehensive protection are additionally exhibited. Moreover, a motor can be controller and protected without any elements outside.
Description
Technical field
The utility model relates to a kind of electric controling element, especially a kind of intelligent vacuum contactor.
Background technology
Vacuum contactor is a kind of critical elements commonly used in the electrical control field, and breaking capacity is high, and arc extinction performance is good, the power supply occasion that is widely used in having relatively high expectations.As a kind of general-purpose device; the conventional vacuum contactor is without any intelligent function; power distribution cabinet with the vacuum contactor assembling is to realize basic control function; also need to increase and start and stop button; comprehensive protector of motor etc., complex circuit, cost is higher; failure rate is also high in the use, has limited applying of vacuum contactor.
Summary of the invention
The purpose of this utility model is the problem that prior art exists is solved, provide a kind of can remote control deciliter, the intelligent vacuum contactor of translator comprehensive protection function.
The technical solution of the utility model is: a kind of intelligent vacuum contactor comprises Current Transformer Assembly, intelligence control circuit board component, vacuum contactor body.The intelligence control circuit board component is installed on the original position that is used for installing cowling panel, can realize rectification, remote control, electromotor integrated protection function.
Beneficial functional of the present utility model is: the utility model has kept structure and the profile installation dimension of conventional vacuum contactor; practical remote control and the intelligent functions of electromotor integrated protection have been increased; the periphery no longer needs any element can realize control and the protection of motor; greatly reduced the application cost of vacuum contactor; simplify the wiring of power distribution cabinet, increased fail safe.
Description of drawings:
Accompanying drawing 1 is schematic block circuit diagram of the present utility model
Embodiment:
Below in conjunction with drawings and Examples the utility model content is described further.
Referring to accompanying drawing 1, intelligent vacuum contactor described in the utility model is comprised of Current Transformer Assembly A, intelligence control circuit board component B, vacuum contactor body C.Wherein intelligence control circuit board component B is comprised of rectification circuit unit 1, remote control circuit unit 2, electromotor integrated protection circuit unit 3.Contactor body C is actuator; current transformer A is used for the induction machine running current; rectification circuit unit 1 among the intelligence control circuit board component B is the used DC power supply of contactor coil with the ac control power supply rectification, and provides remote control circuit unit 2 and electromotor integrated protection circuit unit 3 required DC power supply.Remote control circuit unit 2 can remote control deciliter contactor, has made things convenient for execute-in-place, has also improved fail safe, has stopped the electric shock accidents generation.Electromotor integrated protection circuit unit 3 is analyzed the motor current signal that current transformer A transmit, and the faults such as contingent motor overload, underload, phase shortage are promptly and accurately protected.
