Abstract
The utility model relates to a control device for a power distribution cabinet, comprising a main power supply and a standby power supply, wherein the main power supply is connected with electric equipment through a first breaker, the standby power supply is connected with the electric equipment through a second breaker, the main power supply is connected with the first breaker through a control unit, the standby power supply is connected with the second breaker through the control unit, and the control unit is used for controlling the disconnecting and closing of the first breaker and the second breaker by detecting electric parameters of the main power supply and that of the standby power supply, therefore the control device for the power distribution cabinet can conveniently and quickly switch an input power supply so that the power supply efficiency can be increased and the reliability as well as the continuity of power supply can be improved.
Description
Technical field
The utility model relates to a kind of power distribution cabinet control device.
Background technology
The electric power incoming line of present large and medium-sized factory major step-down substation is generally the double loop inlet wire, and main transformer is 2.The main transformer low-pressure side generally adopts bus section control supply power mode.When certain ring current or transformer fault, can manually this loop be cut off, another loop is thrown, to satisfy the requirement of power supply continuity.This supply power mode, power supply speed is slow, and inefficiency can only satisfy the place that production technology has a power failure in short-term, but for important load places such as picture steel plant, chemical industry, manual switchover can not meet the demands.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of power distribution cabinet control device, to reach quick switching power supply, to satisfy power supply reliability, successional purpose.
In order to solve the problems of the technologies described above the technical solution of the utility model be, a kind of power distribution cabinet control device, comprise main power source, stand-by power supply, described main power source is connected with first transformer by first circuit breaker, described stand-by power supply is connected with second transformer by second circuit breaker, and described main power source is connected with first circuit breaker by control unit, and described stand-by power supply is connected with second circuit breaker by control unit.
Described control unit is the PLC Programmable Logic Controller.
The input of described control unit and main power source, stand-by power supply connects.
The model of described PLC Programmable Logic Controller is the FX2N-16MR-001 type or is equal to the product of model therewith.
The utility model compared with prior art, control unit is by controlling the disconnection and the closure of first circuit breaker and second circuit breaker to the detection of first circuit breaker and the second circuit breaker input/output terminal parameters of electric power, thereby it is convenient, efficiently the input power supply is switched, improve power supplying efficiency, improved the reliability and the continuity of power supply.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further details;
Fig. 1 is the utility model theory diagram;
In Fig. 1,1, main power source, 2, stand-by power supply, 3, first circuit breaker, 4, second circuit breaker, 5, control unit, 6, power consumption equipment.
