The low-voltage comprehensive power distribution box has the advantages that the circuit breaker is driven to realize electric switching on and off by the permanent magnet operating mechanism, and the remote controller is used for realizing long-distance remote control operation; and when a system has transient fault and tripping operation, the permanent magnet operating mechanism is controlled to automatically switch on for restore normal power supply by the remote controller, so that the continuity and reliability of power supply can be improved.
Description
Technical field
The utility model relates to a kind of distribution and reactive power compensator of electrical network, specifically a kind of low-voltage comprehensive distribution box.
Background technology
At present, reactive power compensation is in industry built consensus for the importance and the good result that improve circuit conveying capacity, raising utilization rate of equipment and installations, the loss of reduction line voltage distribution and energy loss, the high pressure compensation of comparing, because of low-voltage circuit more near load point, the benefited circuit of compensation is longer, so the saving energy and decreasing loss effect of low-voltage compensation is more obvious.Low-voltage comprehensive distribution box is by dropping into or excise the reactive power compensation that electric capacity is realized electric power system.Existing low-voltage comprehensive distribution box does not have telemonitoring and controlled function, can't realize the real-time monitoring and the management of electric power system.And existing low-voltage comprehensive distribution box uses contactor to realize the electronic branch that closes as switch element mostly, and its power consumption is big, the use cost height.Normally used distribution box all has automatic power-off protection function, when system breaks down, makes circuit or device powers down, with the circuit or the equipment of protection usefulness.After fault is got rid of, by the manual operation power supply of closing a floodgate again.Outage is longer with the time interval between powering again.According to statistics, permanent fault is generally less than 10% in the system, all the other faults all are because the insulator surface flashover that Lightning Over-voltage causes, short in short-term during strong wind, branch drops on the first-class transient fault that causes of lead, circuit frequently cuts off the power supply, and has caused the continuity and the reliability of power supply low, work about electric power personnel's labour intensity height.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of low-voltage comprehensive distribution box that can realize remote monitoring and the automatic function of supplying power that closes a floodgate again.
Of the present utility modelly be: a kind of low-voltage comprehensive distribution box for solving the problems of the technologies described above the technical scheme that is adopted, be provided with circuit breaker and one group of capacitor that is connected in parallel in the distribution casing, one end of each capacitor is connected with a switching control switch respectively, other end ground connection, the switching control switch is connected with controller, also is provided with permanent-magnet manipulating mechanism and remote controllers that have the gsm wireless communication module in the distribution casing.
Described permanent-magnet manipulating mechanism comprises two operating coils and a drive rod.
The output of described remote controllers is connected with operating coil by drive circuit, and drive rod is connected with the switch driving lever of circuit breaker.
Described switching control switch also is connected in series with air switch.
The beneficial effects of the utility model are: with the main switch of circuit breaker as electric power system, can realize that the electricity operation is sent in overload, short-circuit protection and daily the stopping of distribution line.Cooperate permanent-magnet manipulating mechanism to use, drive circuit breaker by permanent-magnet manipulating mechanism and realize electronic deciliter, and realize the Remote operation by the remote controllers that are provided with.After the transient fault tripping operation appearred in system, remote controllers continued fault-signal is detected, and fault-signal is eliminated back control permanent-magnet manipulating mechanism automatic closing and recovered normal power supply, has improved continuity, the reliability of power supply.Stop sending electric quick and safe simple to operation, both improved operating efficiency, reduced interruption duration again, reduced labour intensity simultaneously, also thoroughly avoided manual operation to stop sending the contact danger of electricity.The remote controllers that are provided with can also be connected with the digital electric meter of electric power system, and the track data remote transmission to the staff, is realized remote meter-reading function.
