Abstract
The utility model relates to a magnetic card meter control box, comprising a tripping loop, a power supply indicating circuit, and an alarm circuit which are arranged between a first fuse and a second fuse. The first fuse and the second fuse are respectively connected with a first control power supply and a second control power supply. The tripping loop comprises a magnetic card meter, a timer, and a time relay which are sequentially connected. The power supply indicating circuit comprises a switch and an indicating lamp which are sequentially connected. The alarm circuit comprises another magnetic card meter and a control switch box buzzer which are sequentially connected. The control box is capable of effectively reducing the work intensity of employees of a power supply station, shortening the power-failure time of users, lowering the production cost, and increasing the economic benefits.
Description
Technical field
The utility model relates to a kind of magnetic card instrument control box.
Background technology
The development of industrial and agricultural production in recent years and people's growth in the living standard, electricity needs is increasing, along with carrying out of city net, the upgrading of rural power grids and rural power grids upgrading engineering, magnetic card instrument is installed more and more, and in actual use, because the defect of magnetic card instrument design causes following consequence: one, due to this kind of magnetic card instrument after power purchase, if the normally closed contact while sending a telegram here again that has a power failure can not be opened in time, if fail the incoming call of discovery system in time, the user can not resume production in time.Two, because secondary circuit does not add insurance, control the upper sluice gate that power supply all is taken at isolating switch simultaneously, magnetic card instrument, without taking deenergization in time after action, causes frequent fault of burning magnetic card instrument contact and circuit breaker trip coil.Three, acoustooptic alarm system is not set, causes the user to pay dues before the arrearage prerequisite, cause the unnecessary power failure of user, affect the normal producer of user and life.Four, the transformer load side only is provided with isolating switch does not have isolation switch, there is no obvious cut-off point during maintenance, must disconnect high pressure in case of necessity, causes the unnecessary trouble of user and potential safety hazard.
Summary of the invention
For above the deficiencies in the prior art, magnetic card instrument control loop to existing magnetic card instrument system improves, the utility model provides a kind of magnetic card instrument control box, has solved above-mentioned series of problems, and the normal use for magnetic card instrument in electric system is laid a good foundation.
The purpose of the present utility model is achieved through the following technical solutions:
The magnetic card instrument control box, comprise the trip(ping) circuit, power indicating circuit and the warning circuit that are arranged between the first and second fuses, described the first fuse and the second fuse are controlled power supply with the first control power supply and second respectively and are joined, described trip(ping) circuit comprises magnetic card instrument, timer and the time relay connected successively, described power indicating circuit comprises switch and the pilot lamp connected successively, and described warning circuit comprises magnetic card instrument, the gauge tap box hummer connected successively.
The utility model has the advantage of:
1, use improved magnetic card instrument, when system blackout, again after power transmission, without the personnel of power supply station, go again manual power transmission, time saving and energy saving.
2, use improved magnetic card instrument, the user, according to alarm condition, can arrive power supply station's electricity payment in time, avoids so incurs loss through delay and produce or household electricity.
3, improved magnetic card instrument, maintenance is convenient, safe and reliable.
The accompanying drawing explanation
Fig. 1: the utility model structure principle chart.
Embodiment
The utility model magnetic card instrument control box comprises trip(ping) circuit, power indicating circuit and the warning circuit be arranged between the first and second fuses, described the first fuse and the second fuse are controlled power supply with the first control power supply and second respectively and are joined, described trip(ping) circuit comprises magnetic card instrument, timer and the time relay connected successively, described power indicating circuit comprises switch and the pilot lamp connected successively, and described warning circuit comprises magnetic card instrument, the gauge tap box hummer connected successively.
Fig. 1 is the utility model structure principle chart, increase control loop insurance and the time relay on original loop, and be provided with sound light alarming circuit, control power supply A and be taken to mutually the circuit breaker electric source, B is taken to the isolating switch load side mutually, like this when system blackout restores electricity, the time relay first electric startup, its contact is closed after a short and small time delay, has prevented that the system incoming call from causing the isolating switch misoperation because magnetic card instrument contact CK can not return in time.Control power supply and be taken to the isolating switch load side because the subscriber arrearage magnetic card instrument sends after trip command the CK junction closure in addition, because the time relay is time closing, moment is opened contact again, the timely cutting-off controlling power supply of circuit breaker trip afterload side dead electricity makes its trip(ping) circuit dead electricity, thereby avoids because of charged thing of burning breaking coil and magnetic card instrument contact of normal phase of isolating switch.
Increased in addition sound light alarming circuit, utilize magnetic card instrument warning contact and gauge tap and hummer to form sound and light alarm, when the user approaches arrearage (according to the setting of magnetic card instrument) send in advance arrearage and report to the police, notify the user to continue to pay dues to avoid to cause power failure because the user can not pay dues in time, incur loss through delay and produce and life.
In the situation that the control box body space allows, the isolating switch load side installs disconnector additional, and during maintenance, being convenient to disconnect has obvious cut-off point, improves maintenance safety, reliability.Must expire and significantly improve by magnetic card instrument control device Reliability of Microprocessor after above transformation, then there is no to burn the thing of contact and coil, security of operation is stable, obtains user's favorable comment.After using improved magnetic card instrument, stop power transmission after magnetic card instrument automatically recover power transmission, alleviated personnel's work in the institute, the while has also guaranteed user's normal electricity consumption.
Should be appreciated that the above detailed description of technical scheme of the present invention being carried out by preferred embodiment is illustrative and not restrictive.Those of ordinary skill in the art modifies reading the technical scheme that can put down in writing each embodiment on the basis of instructions of the present invention, or part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
