Abstract
The utility model relates to an electric switch device, and particularly relates to an automatic tripping dual-power selector switch. A spare power circuit breaker and a common power circuit breaker are arranged inside a shell; a double-throw switch is arranged on the shell; a mounting plate is fixed at the side of the shell; the automatic tripping dual-power selector switch also comprises an automatic tripping mechanism which comprises a sensor, a central processor and a switching module; the output end of the sensor is connected with the input end of the central processor; the output end of the central processor is connected with the input end of the switching module; and the switching module is connected with the spare power circuit breaker and the common power circuit breaker respectively. According to the structure, the temperature sensor is utilized to detect an external temperature and transmit the detected temperature to the central processor; the central processor controls the switching module to perform automatic tripping as long as the external temperature reaches a certain value; and therefore, the circuit is directly cut off when a fire hazard is generated, and no short circuit is generated to aggravate the fire hazard.
Description
Technical field
The utility model relates to a kind of electrical apparatus-switching device, especially a kind of automatic trip double power supply converting switch.
Background technology
Twin-power switch (abbreviation duplicate supply) mainly is to adopt breaker of plastic casing (CB level) or isolating switch (PC level) element to form.According to the regulation of standard GB/T14048.11-2008, be divided into CB level, PC level and CC level.As executive component, be equipped with single-chip microcomputer and be the automatic controller of core and the controlling organization of band electromechanical interlock, be a kind of perfect performance, safe and reliable, automaticity is high, the scope of application is wide twin-power switch.Product is applicable to and exchanges 50/60Hz, 690V and following, rated current is in the electric power system of 6A to 1250A and following two-way power supply (power supply N commonly used and stand-by power supply or generator power supply R), because of one road power supply break down (have a power failure, under-voltage, overvoltage, the phase failure, frequency shift (FS)) carry out the automatic switchover between the power supply, to guarantee the reliability and the fail safe of power supply.Be widely used in skyscraper, sub-district, hospital, airport, harbour, fire-fighting, metallurgy, chemical industry, weaving etc. and do not allow the important place that has a power failure, realize that unattended operation powers continuously.
But twin-power switch does not in the market all have the device of hidden danger control, because the place at power supply place is the high-risk zone of fire, especially the fire condition in zone, if all be to patrol and examine by personnel, waste of human resource is very serious, and therefore on-the-spot the detection just becomes a difficult problem, even supervising device is arranged, can not take precautions against in possible trouble, work as breaking out of fire, can't automatic trip, cause the fire can not be in time controlled, even can allow fire more serious.
Summary of the invention
The purpose of this utility model is, a kind of safe, automatic trip double power supply converting switch that can automatic trip is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic trip double power supply converting switch, comprise auxiliaries-supply circuit-breaker, power circuit breaker commonly used, mounting panel, double-throw switch, housing, auxiliaries-supply circuit-breaker and power circuit breaker commonly used are arranged in the housing, double-throw switch is arranged on the housing, mounting panel is fixed on the housing side, also comprise automatic trip mechanism, automatic trip mechanism comprises transducer, central processing unit, the combined floodgate module, the output of transducer is connected with the input of central processing unit, the output of central processing unit is connected with the input of combined floodgate module, the combined floodgate module respectively with auxiliaries-supply circuit-breaker, power circuit breaker commonly used connects.
Of the present utility modelly further be set to: described transducer is a temperature sensor, and temperature sensor is fixedly installed on the double-throw switch top.
Of the present utility modelly further be set to: be provided with protective cover on temperature sensor, protective cover is provided with the air-vent of net distribution.
Said structure utilizes temperature sensor to detect external temperature and is transferred in the central processing unit, as long as external temperature reaches certain temperature, central processing unit is just controlled the automatic trip of combined floodgate module, even breaking out of fire so, circuit directly cuts off the power supply, and can not be short-circuited makes fire more serious.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the stereogram of present embodiment;
Fig. 2 is the schematic diagram of present embodiment.
Embodiment
With reference to figure 1; Fig. 2 as can be known; a kind of automatic trip double power supply converting switch; comprise auxiliaries-supply circuit-breaker 2; power circuit breaker 3 commonly used; mounting panel 4; double-throw switch 5; housing 1; auxiliaries-supply circuit-breaker 2 is arranged in the housing 1 with electric power disconnection 3 devices commonly used; double-throw switch 5 is arranged on the housing 1; mounting panel 4 is fixed on housing 1 side; also comprise automatic trip mechanism; automatic trip mechanism comprises temperature sensor 6; central processing unit; the combined floodgate module; the output of temperature sensor is connected with the input of central processing unit; the output of central processing unit is connected with the input of combined floodgate module; the combined floodgate module respectively with auxiliaries-supply circuit-breaker 2; power circuit breaker 3 commonly used connects; temperature sensor 6 is fixedly installed on double-throw switch 5 tops; be provided with protective cover 7 on temperature sensor 6, protective cover 7 is provided with the air-vent 71 of net distribution.
Obviously, the foregoing description only be for explanation clearly done for example, and be not qualification to execution mode.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And conspicuous variation of being extended out thus or change still are in the protection range of the present utility model.
