Description
Technical field
The present invention relates to a kind of explosion switch state detector, specifically is a kind ofly to utilize electronic circuit technology to realize the explosion switch branch, close the checkout gear of state indication.
Background technology
Explosion switch is the special machine switch that a kind of explosive drives, its branch, the mode of closing are different with the common mechanical switch, the common mechanical switch is to make moving contact realize that through certain stroke contact closure and separately, the movement travel of mechanical linkage or transmission mechanism are easy to the auxiliary node that just can obtain the indicator cock branch, close state by travel switch by energy storage and linkage.The combined floodgate of explosion switch then is by manually contact being compressed with bolt, and the switch disjunction then is by cap sensitive explosive, section breaker under the great force of the detonation wave that explosive charge produces.This special branch, the mode of closing can't adopt traditional mechanical transmission mechanism, by travel switch come indicator cock branch, close state; In addition, because the disjunction of switch contact realizes by explosive charge, can't utilize also that the placement force transducer waits the sense switch state on contact.
Summary of the invention
The purpose of this invention is to provide a kind of explosion switch state detector, solve exactly under the irrealizable condition of traditional detection device, conveniently realize the explosion switch branch, close status detection and indication by the condition checkout gear that directly adds the use of electronic circuit and relay synthetic at the explosion switch two ends, this device also can be used for common mechanical switch branch, closes status detection.
Technical scheme of the present invention is as follows:
Explosion switch state detector, it is characterized in that having the input termination alternating current 220V power supply of rectification unit, output has two branch road parallel connections, article one, propping up route resistance R 1 and light-emitting diode D1 series connection constitutes, another route resistance R 2, R3, R4 and bridge-type high-voltage diode unit and be connected on fixed contact B1, the moving contact B2 at explosion switch two ends and the input of optic coupling element is composed in series, series connection links to each other with the positive and negative electrode of direct current 24V power supply respectively with light-emitting diode D2 by relay coil at the output two ends of optic coupling element.
The two ends of described relay coil also are parallel with diode.
Checkout gear mainly is made of rectification unit, bridge-type high-voltage diode unit, optic coupling element and low-voltage direct relay etc.Output 36V direct voltage after the rectification of alternating current 220V power supply process rectification unit, the series circuit power supply of low-voltage direct output to forming by the input of high pressure bridge diode unit, explosion switch, big resistance and optocoupler components; Its basic functional principle is: when switch is in closure state, having electric current in the optocoupler components input passes through, the output conducting of the optocoupler components that connect with the low-voltage direct relay coil this moment, pass through electric current in the relay coil, make and relay normally open node closure show that explosion switch is in closure state.Have no progeny when the switch branch, the optocoupler components input does not have electric current to pass through, and at this moment its output transfers cut-off state to by conducting, and the relay coil dead electricity is often opened node and recovered normal open mode, shows that explosion switch is in the disjunction state.
The outstanding advantage of apparatus of the present invention is to utilize simple electronic circuit and relay node to realize solving the difficult point that detects the explosion switch branch, closes state easily; In addition, the high voltage that has produced when having realized the isolating switch disjunction by utilization bridge-type high-voltage diode unit and optocoupler components, but the highest isolation voltage reaches more than the 5000V; This device also can replace traditional travel switch to be applied to the common mechanical switch as state indicating device.
Description of drawings
Fig. 1 is an electronic-circuit diagram of the present invention.
Embodiment
Concrete use below in conjunction with 1 pair of apparatus of the present invention of accompanying drawing is described in further detail.
As shown in Figure 1, rectification unit 1 input A1, A2 connect the alternating current 220V power supply, output has two branch road parallel connections, article one, propping up route resistance R 1 and light-emitting diode D1 constitutes as the rectification unit indication of working normally, another main branch road is by resistance R 2, R3, R4 and bridge-type high-voltage diode unit 2 and be connected on B1, the B2 at explosion switch two ends and the input of optic coupling element 3 is composed in series, B1 termination switch fixed contact wherein, B2 termination switch movable contact.Series connection links to each other with the positive and negative electrode of direct current 24V power supply respectively with light-emitting diode D2 by relay coil 4 at the output two ends of optic coupling element 3.
When additional power source is connected, the luminous tube of diode D1 is luminous, show that rectification unit 1 starts working, this moment is if explosion switch is in closure state, then by the input of electric current by optic coupling element 3, at this moment optic coupling element 3 output conductings, relay 4 coils flow through electric current, often open the node closure, and diode D2 luminous tube is luminous simultaneously, show that the relay node is closed, explosion switch is in conducting state; When switch is in off-state, because the input of optic coupling element 3 does not have electric current to flow through, its output ends all the time, relay coil 4 does not have electric current to pass through, often opening node is normal off-state, and light-emitting diode D2 does not work, and shows that explosion switch is in off-state.
