Reliability of the automatic transfer switching equipment can be enhanced.
Description
Technical field:
The utility model patent relates to a kind of electrical interlock control device of transfer switching equipment.
Background technology:
Transfer switching equipment is in many important events and do not allow the unit of power cut-off to use in a large number.For guaranteeing continuously reliable power supply, then need transfer switching equipment to have reliable electrical interlock control device, promptly mechanical device and electronic-controlled installation can effectively combine, and reach the interlocking interlocking and reliably switch purpose.
Transfer switching equipment is generally by two executive components, control unit, and the transmission switching device shifter constitutes; The validity of the exchange of the positional information between control device and transmission switching device shifter and the executive component and reliability just become and just become the reliable key of switching of transfer switching equipment, otherwise can cause transfer switching equipment misoperation, be failure to actuate, the serious transfer switching equipment that can cause burns, and may cause the heavy losses of property or casualties.
Transfer switching equipment generally has three kinds of location statuss: power supply commonly used closes a floodgate, and stand-by power supply closes a floodgate, two minutes positions.What existing transfer switching equipment major part adopted is the annex of executive component, as the feedback information of location status; These class methods have significant limitation, and the annex price height of executive component, and the machinery damping vibration is big when disconnecting with closure, with the main contact poor synchronization, have a strong impact on the judgement of control device location information, can't get up with the effective connection of transmission switching device shifter, be to cause the insecure key factor of transfer switching equipment, has a strong impact on the quality for distribution.
Summary of the invention:
In view of the problem of above-mentioned prior art transfer switching equipment, the purpose of the utility model patent is to provide a kind of reliable and stable electrical interlock control device.
The purpose of the utility model patent adopts following technical proposals to realize:
The electrical interlock control device of this transfer switching equipment is by forming with taper knob 4 sensitive switches 5 sensitive switches 6 sensitive switches 7 sensitive switches 8 left plates 9 right plates 10 wire harness 11 wire harness 12 wire harness 13 wire harness 14 electric control units 15 of taper knob 3 driving switchs of executive component 1 executive component 2 driving switchs; The taper knob 3 of driving switch with carry out switch 1 and cooperate, left plate 9 is provided with the fixedly hole of sensitive switch 5 and sensitive switch 6, right plate 10 is provided with the fixedly hole of sensitive switch 7 and sensitive switch 8; The pressing plate of sensitive switch 5 and sensitive switch 6 contacts with the taper knob 3 of driving switch, and the pressing plate of sensitive switch 7 and sensitive switch 8 contacts with the taper knob 4 of driving switch; Sensitive switch 5 and sensitive switch 6 send the position signalling of executive component 1 to electric control unit 15 by wire harness 11 wire harness 12 accurately, and sensitive switch 7 and sensitive switch 8 send the position signalling of executive component 2 to electric control unit 15 by wire harness 13 wire harness 14 accurately; , drive relevant apparatus and finish handoff functionality by logic determines by electric control unit 15.
Description of drawings:
Fig. 1 left side constitutional diagram
The right constitutional diagram of Fig. 2
Fig. 3 electric control unit electrical schematic diagram
Code name implication among the figure: the taper knob 5 sensitive switches 6 sensitive switches 7 sensitive switches 8 sensitive switches 9 left plates 10 right plates 11 wire harness 12 wire harness 13 wire harness 14 wire harness 15 electric control units 16 triple-pole double throw relays 17 power supply N 18 stand-by power supply N commonly used of taper knob 4 driving switchs of 1 executive component, 2 executive components, 3 driving switchs
Embodiment:
As Fig. 1 Fig. 2, when transfer switching equipment is positioned at commonly used power supply closing position, executive component 1 closure, executive component 2 disconnects, sensitive switch 6 closures, sensitive switch 5 disconnects, sensitive switch 7 closures, sensitive switch 8 disconnects; When transfer switching equipment was positioned at the stand-by power supply closing position, executive component 1 disconnected, executive component 2 closures, and sensitive switch 6 disconnects, sensitive switch 5 closures, sensitive switch 7 disconnects sensitive switch 8 closures; When transfer switching equipment was positioned at two branchs position, executive component 1 disconnected, and executive component 2 disconnects, and sensitive switch 6 disconnects, sensitive switch 5 closures, sensitive switch 8 closures, sensitive switch 7 disconnections; Be that transfer switching equipment is in arbitrary position, 4 sensitive switches can provide one group of reliable position signal to be transferred to electric control unit 15 by wire harness 11 wire harness 12 wire harness 13 wire harness 14, electric control unit 15 is made logical action according to the switch current location by triple-pole double throw relay 16, drives switching device shifter and realizes reliable the switching.
As long as sensitive switch 5 and sensitive switch 6 are provided with taper knob 3 both sides of position at driving switch, as long as sensitive switch 7 and sensitive switch 8 are provided with taper knob 4 both sides of position at driving switch, as long as one group of signal of output, then its number of winning the confidence mode is not done special qualification, taper knob shape to sensitive switch type and driving switch is not done special qualification, as long as be positioned at the rotating part appropriate location, then in not breaking away from this patent purport scope, can suitably change; Electric control unit then can suitably change in not breaking away from this patent purport scope as long as the signal of getting is adopted same processing mode.
