Abstract
The utility model relates to a circuit control device, which belongs to the field of industrial devices. The circuit control device comprises a circuit breaker and a motor which are sequentially connected in a circuit, and is characterized in that an ammeter, an AC contactor and a thermal overload protector which are sequentially added between the circuit breaker and the motor. The circuit control device not only has the characteristics of timeliness in overload and open-phase discovery, easiness in current intensity observation and security in electricity consumption, but also ensures normal operation of electric appliances in a slaughtering workshop, protects human and property security, and improves the working efficiency.
Description
Technical field
The utility model relates to a kind of circuit control device, belongs to the commercial plant field.
Background technology
On electrotechnics; Contactor is a kind of automation switch that is used for being switched on or switched off load-carrying alternating current-direct current main circuit or big volume controlled circuit, and major control also is used for other electrical loads in addition to liking motor; Like electric heater; Electric welding machine, lighting apparatus is one of critical elements in the automatic control system.
In the circuit control device of slaughter hall, there are not ammeter, A.C. contactor and thermal overload protection device, if, be prone to burn, both the person and property safety were threatened especially when being that motor does not quit work when transshipping, make again to produce to be affected.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of Electrical Safety, protection motor are provided, and overload, phase shortage, the size of current circuit control device that is easy to observe.
The utility model solves the technical scheme that its technical problem adopted:
Described circuit control device comprises the circuit breaker and the motor that are connected in turn in the circuit, and its characteristics are: between circuit breaker and motor, set up ammeter, A.C. contactor and thermal overload protection device successively.
The ammeter of setting up makes operating personnel observe electric current and is more prone to; Circuit can not only connected and cut off to A.C. contactor, but also have the effect of low-voltage release guard, and A.C. contactor control capacity is big; When making temperature rise to the operating temperature of thermal overload protection device when the heating of motor failover; The thermal overload protection device is heated and produces internal stress and action rapidly; Open circuit plays protection motor effect thereby cut off the electricity supply, when being dropped to the specified reset temperature value of thermal overload protection device by the protection motor; The thermal overload protection device returns to the initial condition closing of contact, and motor recovers operate as normal.
The beneficial effect that the utility model had is:
The utility model is set up ammeter, A.C. contactor and thermal overload protection device successively between circuit breaker and motor; Not only have overload, phase shortage can in time be found; Size of current is easy to observe, the characteristics of Electrical Safety, and when having guaranteed the normal operation of slaughter hall electrical equipment; Also protect the safety of the person and property, improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, circuit breaker; 2, ammeter; 3, A.C. contactor; 4, thermal overload protection device; 5, motor.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, described circuit control device comprises the circuit breaker 1 and motor 5 that are connected in turn in the circuit, and its characteristics are: between circuit breaker 1 and motor 5, set up ammeter 2, A.C. contactor 3 and thermal overload protection device 4 successively.
The ammeter of setting up 2 makes operating personnel observe electric current and is more prone to; Circuit can not only connected and cut off to A.C. contactor 3, but also have the effect of low-voltage release guard, and A.C. contactor 3 control capacity are big; When making temperature rise to the operating temperature of thermal overload protection device 4 when the heating of motor 5 failover; Thermal overload protection device 4 is heated and produces internal stress and action rapidly; Open circuit plays the effect of protection motor 5 thereby cut off the electricity supply, when being dropped to the specified reset temperature value of thermal overload protection device by protection motor 5; Thermal overload protection device 4 returns to the initial condition closing of contact, and motor 5 recovers operate as normal.
The utility model is set up ammeter 2, A.C. contactor 3 and thermal overload protection device 4 successively between circuit breaker 1 and motor 5; Characteristics with Electrical Safety; And when having guaranteed the normal operation of slaughter hall electrical equipment, also protected the safety of the person and property, improved operating efficiency.
