Abstract
The utility model relates to a common AC dual-supply-switching lighting distribution box applied in transformer substations and power plants, and mainly applied to the controlled usage of the power supply of an indoor lighting lamp. The main electrical loop of the common AC dual-supply-switching lighting distribution box comprises a primary control circuit and a secondary control circuit. The primary control circuit comprises a breaker QF1, breakers Q1-Q6, and a contactor KM1. The secondary control circuit comprises a breaker QF2, a time relay KS, a contactor KM1, a contactor KM2, an indicating lamp H1 and an indicating lamp H2. The common AC dual-supply-switching lighting distribution box is designed to satisfy the indoor illumination requirement, especially the illumination requirement in a key equipment plant. When one lighting power supply circuit breaks down, the lighting distribution box automatically switches to the other lighting power supply circuit. Therefore, the uninterrupted power supply for supplying power to lighting lamps is enabled.
Description
Technical field
The common interchange duplicate supply that the utility model relates to a kind of transformer station, power plant use switches light distribution box, and the control that is mainly used in indoor illumination light fitting power supply is used.
Background technology
The construction in transformer station, power plant is at present more and more, and capacity is increasing, and along with the continuous increase of place, factory building is more and more, and patrol task amount is just increasing.
Summary of the invention
When the utility model has fault in order to solve transformer station, the indoor road mains lighting supply in power plant, automatically switch to another road power supply, guarantee that lighting does not have a power failure, propose common interchange duplicate supply and switch light distribution box.
For realizing above goal of the invention, the utility model proposes following technical scheme: common interchange duplicate supply switches light distribution box, its main body electric loop comprises control loop, secondary control loop, one time control loop arranges circuit breaker Q F1, circuit breaker Q 1～Q6 and contactor KM1, secondary control loop is provided with circuit breaker Q F2, time relay KS, contactor KM1, contactor KM2, indicator light H1, indicator light H2, the end of incoming cables of circuit breaker Q F1 and the A end that exchanges end of incoming cables, B end, C holds connection, the leading-out terminal of circuit breaker Q F1 is series contactor KM1 normally closed switch successively, contactor KM1 coil best friend flows to the N end of line end, contactor KM1 normally closed switch, the second series circuit that the first series current cross-over connection that contactor KM1 coil forms has contactor KM1 normal open switch and indicator light H1 to be in series, time relay KS normal open switch and contactor KM2 coil form the 3rd series circuit, contactor KM2 normal open switch and indicator light H2 form the 4th series circuit, the 3rd series circuit, the 4th series circuit, time relay KS coil three is connected across circuit breaker Q F2 leading-out terminal and exchanges between the N end of end of incoming cables after series contactor KM1 normal open switch again after forming parallel circuits.
Feature of the present utility model and beneficial effect: consider room lighting, especially the requirement of emphasis equipment illumination of plant building, at this, adopt and exchange duplicate supply switching light distribution box, when one tunnel mains lighting supply has fault, automatically switch to another road power supply, realized the uninterruption power source to lighting power supply.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment electrical wiring schematic diagram.
Embodiment
Referring to accompanying drawing 1, the utility model embodiment exchanges duplicate supply and switches light distribution box, its main body electric loop comprises control loop, secondary control loop, one time control loop arranges circuit breaker Q F1, circuit breaker Q 1～Q6 and contactor KM1, secondary control loop is provided with circuit breaker Q F2, time relay KS, contactor KM1, contactor KM2, indicator light H1, indicator light H2, the end of incoming cables of circuit breaker Q F1 and the A end that exchanges end of incoming cables, B end, C holds connection, the leading-out terminal of circuit breaker Q F1 is series contactor KM1 normally closed switch successively, contactor KM1 coil best friend flows to the N end of line end, contactor KM1 normally closed switch, the second series circuit that the first series current cross-over connection that contactor KM1 coil forms has contactor KM1 normal open switch and indicator light H1 to be in series, time relay KS normal open switch and contactor KM2 coil form the 3rd series circuit, contactor KM2 normal open switch and indicator light H2 form the 4th series circuit, the 3rd series circuit, the 4th series circuit, time relay KS coil three is connected across circuit breaker Q F2 leading-out terminal and exchanges between the N end of end of incoming cables after series contactor KM1 normal open switch again after forming parallel circuits.
Circuit breaker is generally closure state, and the main protections such as the short circuit current protection of current supply circuit are realized by circuit breaker, contactor only as switch loop use.Under normal operating conditions, all circuit breakers are all closed, and contactor KM1 loop is connected, each output loop power supply; During QF1 dead electricity, contactor KM1 loop disconnects, and after time relay KS time delay, contactor KM2 loop is connected, and each output loop continues power supply.
Above embodiment is only for illustration of the utility model; but not to restriction of the present utility model; person skilled in the relevant technique; without departing from the spirit and scope of the present invention; can also make various conversion or modification; therefore all technical schemes that are equal to, all fall into protection range of the present utility model.
