Abstract
A solenoid valve power supply control loop is provided. The control loop comprises a breaker, a transistor capacitor and rectifier bridges, the loop is characterized in that the breaker is used for introducing three-phase electricity as a power supply and connected with the transistor capacitor, leading-out pins of the transistor capacitor are then connected with the breaker and connected with the rectifier bridges in series. The rectifier bridges are connected with the transistor capacitor in parallel after being connected with the breaker respectively. The loop is simple in line and low in costs, is convenient and practical and has strong compatibility, the three-phase power supply can be directly and selectively chosen, no external power supply is needed, and opening and closing of a solenoid valve power supply can be conveniently controlled.
Description
Technical field
The utility model relates to electric equipment field, specifically a kind of power of electromagnetic valve control loop.
Background technology
Regulator cubicle is to be processed to protect the cupboard of components and parts normal operation by steel matter.Regulator cubicle is made material and generally is divided into two kinds of hot rolled steel plate and cold-rolled steel sheets.Cold-rolled steel sheet relatively hot rolled steel plate more material is soft, is more suitable for the making of regulator cubicle.The regulator cubicle chemical industry that is mainly used in of many uses, environmental protection industry (epi), electric power system, metallurgical system; industry, nuclear power industry, security against fire monitoring; transportation industry etc., its effect are that electrical control is arrived each position of loading with power distribution, and carry out power-off protection when short circuit, overload and electric leakage.Frequent species has the board-like regulator cubicle of stationary plane, protection regulator cubicle, drawer type regulator cubicle and power and lighting regulator cubicle etc.
Because the effect of regulator cubicle need to be arrived power distribution each position of loading, and carry out power-off protection when short circuit, overload and electric leakage.Because regulator cubicle often need to be used power of electromagnetic valve, but also there is no a kind of general power of electromagnetic valve control loop at present.
Summary of the invention
The utility model provides a kind of circuit simple, with low cost, convenient and practical power of electromagnetic valve control loop for above technical problem.
The utility model is achieved through the following technical solutions.
A kind of power of electromagnetic valve control loop comprises circuit breaker, transistor capacitance, rectifier bridge, it is characterized in that, circuit breaker is introduced three-phase electricity as power supply, then is connected with transistor capacitance, and the transistor capacitance leading foot is connecting breaker again, then connects with rectifier bridge.A plurality of rectifier bridges respectively with can access transistor electric capacity in parallel after circuit breaker is connected.
The utility model circuit is simple, with low cost, convenient and practical, and compatible strong, can directly access three phase mains by selectivity, need not additional power source, can conveniently control the switching of rectifier bridge.
Description of drawings
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
The 1-circuit breaker, 2-transistor capacitance, 3-rectifier bridge.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of power of electromagnetic valve control loop comprises circuit breaker 1, transistor capacitance 2, rectifier bridge 3, it is characterized in that, circuit breaker 1 is introduced three-phase electricity as power supply, then be connected with transistor capacitance 2, transistor capacitance 2 leading foots are connecting breaker 1 again, then connects with rectifier bridge 3.A plurality of rectifier bridges 3 respectively with can access transistor electric capacity 2 in parallel after circuit breaker 1 is connected.
During use, at first introduce three-phase electricity as power supply by circuit breaker 1, then be connected with transistor capacitance 2, when only having a power of electromagnetic valve, directly with after rectifier bridge 3 connecting breakers 1, in parallel with transistor capacitance 2.When a plurality of power of electromagnetic valve is arranged, first independent rectifier bridge 3 is connected with circuit breaker 1 respectively, after then being connected with rectifier bridge 3 parallel connections of circuit breaker 1, then be connected with transistor capacitance 2, can easily realize the independent control of power of electromagnetic valve.And, because transistor capacitance 2 front ends as the control loop power supply are added with circuit breaker 1, break-make when also can realize a plurality of power of electromagnetic valve.
The utility model circuit is simple, with low cost, convenient and practical, and compatible strong, can directly access three phase mains by selectivity, need not additional power source, can conveniently control the switching of power of electromagnetic valve.
