Abstract
The utility model relates to a releasing and alarm device for a pressure sensitive assembly of a lighting protector, which comprises a case body. The inside of the case body is provided with a pressure sensitive resistor and a reed switch which is composed of an alarm elastic trip. An electrode of the pressure sensitive resistor is connected with an external leading electrode and the other electrode of the pressure sensitive resistor is welded with an elastic tripping electrode. The elastic tripping electrode goes around a rotor plate of the reed switch and extends to the external side of the case body. The reed switch is under the state of conduction by the pressure of the elastic tripping electrode. When the pressure sensitive resistor fails, the device makes the pressure sensitive resistor released from a circuit promptly and reliably. Simultaneously, the device generates an alarm signal by the alarm elastic trip. The tripping is sensitive and the alarm is reliable. In addition, the structure is simple and the device is favorable for commercial process.

Technical field
The utility model relates to the piezo-resistance assembly that uses in the lightning protection device, specifically is a kind of device that makes the piezo-resistance dropout and produce the Failure Alarm signal in the pressure responsive resistor failure process.
Background technology
For the lightning protection of power-supply system, be extensive use of piezo-resistance at present.Adopt piezo-resistance that power-supply system is carried out lightning protection, below two problems must solve reliably: 1, piezo-resistance often short-circuit lost efficacy, must in time from electrical network, break away from, otherwise will produce overload, even cause the generation of fire.2, behind the pressure responsive resistor failure, the lightning protection device how to notify administrative staff to change inefficacy in time guarantees the normal operation of protected equipment.
To above problem, different solutions is arranged in the market.As: the short circuit after the mode of the two ends of piezo-resistance series connection temperature safety tube, electric current protective tube is avoided losing efficacy, and the scheme that the sticking temperature fuse is reported to the police on the piezo-resistance body.But these scenario-frame complexity, complex production process are unfavorable for suitability for industrialized production.
Summary of the invention
The purpose of this utility model is the above-mentioned defective that overcomes prior art, a kind of simple in structure, thread off dropout and warning device sensitive, the pressure-sensitive assembly of reliable alarm lightning protection device are provided, guarantee that the piezo-resistance that lost efficacy in time, break away from and output alarm signal from circuit reliably.
The dropout and the warning device of the pressure-sensitive assembly of the utility model lightning protection device comprise box body 7, the reed switch that piezo-resistance 2 is set in the described box body 7 and constitutes by alarm spring plate 5,6, one electrode 3 of piezo-resistance 2 connects outer electrode 8, another electrode 1 welding elastic disengaging electrode 4 of piezo-resistance 2, elastic disengaging electrode 4 is walked around the moving plate of reed switch and is extended to outside the box body 7, and reed switch is subjected to the pressure of elastic disengaging electrode 4 to be in conducting state.Produce the melts soldering tin that a large amount of heats makes electrode 1 with elastic disengaging electrode 4 welds of piezo-resistance 2 in piezo-resistance 2 failure procedures, elastic disengaging electrode 4 flicks, fault piezo-resistance 2 is broken away from from circuit, the pressure of 4 pairs of reed switches of elastic disengaging electrode is removed simultaneously, make reed switch become open-circuit condition, produce alarm signal by conducting state.
The dropout of the pressure-sensitive assembly of this lightning protection device and warning device in time, reliably piezo-resistance is broken away from, produce alarm signal by reed switch simultaneously from circuit when pressure responsive resistor failure, its thread off sensitive, report to the police reliable.It is simple in structure in addition, helps suitability for industrialized production.

Embodiment
Elaborate below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, the dropout of the pressure-sensitive assembly of this lightning protection device and warning device comprise box body 7, piezo-resistance 2 is set and by alarm spring plate 5 in the described box body 7,6 reed switches that constitute, wherein, alarm spring plate 5 is a moving plate, alarm spring plate 6 is a still, piezo-resistance 2 both sides are welding electrode 1 and electrode 3 respectively, the right shell wall of box body 7 is installed outer electrode 8, outer electrode 8 welds and extends to outside the box body 7 with the electrode 3 of piezo-resistance 2, the left shell wall of box body 7 is installed elastic disengaging electrode 4, elastic disengaging electrode 4 walk around alarm spring plate 5 the lower end and with electrode 1 welding of piezo-resistance 2, elastic disengaging electrode 4 other ends place outside the box body 7, the lower end of the alarm spring plate 5 (moving plate) of described reed switch is in contact with one another by the pressure of elastic disengaging electrode 4 and alarm spring plate 6 (still), make reed switch be in conducting state, alarm spring plate 5,6 upper end extends to outside the box body 7 by a lead separately.
Be with high pressure resistant insulation sleeve pipe 9 on the above-mentioned elastic disengaging electrode 4, power circuit and alarm circuit are isolated.Also can the isolation that cross-over block is realized power circuit and alarm circuit be set in elastic disengaging electrode 4 and alarm spring plate contact position.
The dropout of the pressure-sensitive assembly of this lightning protection device and the manufacturing process of warning device are as follows:
Electrode 1 and electrode 3 are welded in piezo-resistance 2 both sides respectively, suit high pressure resistant insulation sleeve pipe 9 on elastic disengaging electrode 4 is respectively charged into piezo-resistance 2, alarm spring plate 5, alarm spring plate 6, elastic disengaging electrode 4, outer electrode 8 position corresponding in the box body 7 again; Electrode 1 with piezo-resistance 2 reliably welds with scolding tin at I place with elastic disengaging electrode 4 then, and the electrode 3 and the outer electrode 8 of piezo-resistance 2 reliably welded with scolding tin at the II place.
With reference to Fig. 3,4, the dropout of the pressure-sensitive assembly of this lightning protection device and the dropout of warning device and alarm principle are as follows:
During use, outer electrode 8 and the protected power circuit of elastic disengaging electrode 4 accesses with this device are connected to its alarm spring plate 5,6 in the warning circuit.
A large amount of heats that pressure-sensitive ceramics produces in piezo-resistance 2 failure procedures rise I place temperature rapidly, after the I place melts soldering tin, elastic disengaging electrode 4 flicks, and elastic disengaging electrode 4 disconnects with the electrode 1 of piezo-resistance 2, and fault piezo-resistance 2 is broken away from from power circuit.At this moment, the pressure of the alarm spring plate 5 (moving plate) of 4 pairs of reed switches of elastic disengaging electrode is removed, and alarm spring plate 5 (moving plate) and alarm spring plate 6 (still) are disengaged, and reed switch becomes open-circuit condition by conducting state, produces alarm signal.
