Because the equipment of the power supply classes such as ups power, EPS power supply, variable-frequency power sources, alternating current steady voltage plug all belongs to voltage source The power supply of type, and back-up power source is also voltage-source type power supply, both can not be directly in parallel, therefore inspection switch Using method as follows: the mechanical type manual interlocking techniques of (1) inspection switch: use mechanical part prevent output switch And inspection switch is closed at, block the make position of inspection switch by installing a metal baffle additional so that it is cannot arbitrarily close Close, when needing inspection switch to close, it is necessary to disconnect output switch, unclamp metal baffle fixed screw, metal baffle is slided into The position of output switch, could close inspection switch, and now output switch is blocked cannot be closed by baffle plate, and vice versa, It is achieved in that the interlocking of inspection switch and output switch.The shortcoming of this kind of method is: the most this mechanical interlocks uses Be frame for movement, complex operation, waste time and energy;Secondly mechanical part unavoidably weares and teares when operation, frame for movement fault Rear inconvenience releases interlocking;(2) the manual interlocking techniques of the electronic type of inspection switch: use hand-manipulated and that panel is embedded electronics Interlock function, prevents output switch and inspection switch from simultaneously turning on;During manual closedown power-supply device, the electronics that panel is embedded The load of power-supply device is switched to back-up power source and powers by interlock logic circuit, then closes inspection switch, by standby confession Electricity power supply is connected directly to the outfan of power-supply device, finally disconnects output switch, enters into maintenance model.Lacking of this kind of method Point is: manual handling thereof is loaded down with trivial details, easily causes the accident of power supply of output short-circuit when making a fault.
Summary of the invention
It is an object of the invention to the drawbacks described above overcoming prior art to exist, it is proposed that a kind of power-supply device inspection switch Self interlocking device, linkage interlocked by automatically controlling inspection switch and contact, position, solve mechanical interlocks, operate numerous Trivial, rapid wear and be difficult to the problem repaired, and solve the manual interlocking techniques of electronic type and easily cause circuit short because of maloperation Road and the problem of injury device.
The present invention is to use following technical scheme to realize: the self interlocking device of a kind of power-supply device inspection switch, bag Including main electricity, power supply equipment, STS switching equipment, use electric loading and back-up power source, main electricity is by supplying Electricity power-supply device is connected to STS and switches equipment, and back-up power source is directly connected to STS and switches equipment, main electricity and standby Power supply is parallel with one another, and STS switches equipment connection electric loading, also includes inspection switch and contact, position, inspection switch across Be connected on back-up power source and with between electric loading, inspection switch and contact, position be linkage interlocked, position contacts status by every From testing circuit, collection signal being passed to MCU processor, MCU processor connects control power-supply device and control by performing circuit STS processed switches equipment.
Further, MCU processor, according to the location status of inspection switch, is automatically adjusted the mode of operation of power supply output, During inspection switch Guan Bi, power supply output is at back-up power source output mode, and when inspection switch disconnects, power supply exports in main power supply Power supply output mode.
Further, MCU processor is provided with the hysteresis loop comparator preventing unexpected switchback critical flutter.
Further, power supply equipment includes ups power, EPS power supply, variable-frequency power sources and alternating current steady voltage plug.
Further, it is provided with input switch between main electricity and power supply equipment.
Further, it is provided with input switch between back-up power source and STS switching equipment and inspection switch.
Further, STS switches equipment and is provided with output switch between electric loading.
The invention has the beneficial effects as follows:
(1) the self interlocking device of power-supply device inspection switch of the present invention, mechanical interlock, simple to operate, Mechanical wear-out part, extension device service life;
(2) the self interlocking device of power-supply device inspection switch of the present invention, it is not necessary to according to set flow operations, with Meaning operation is also not result in device damage;
(3) the self interlocking device of power-supply device inspection switch of the present invention, improves the reliability of power-supply device, appearance Mistake, the power supply switching of whole maintenance process is free of discontinuities, improves power supply quality.
Accompanying drawing explanation
Fig. 1 is the electrical schematics of the present invention.
Fig. 2 is the testing circuit electrical schematics using light-coupled isolation.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
The present invention relates to the field such as Power Electronic Technique, Analog Electronics Technique, this technology can be applicable to ups power, EPS electricity Source, variable-frequency power sources, alternating current steady voltage plug etc., use when being a kind of overhaul of the equipments is switched fast and interlocking techniques.
