Description

Dual self protection type's power lightning protection module

One, technical field

The utility model is a kind of surge protector that is used for the low-voltage power power-supply system, belongs to the technical field that protection electrical equipment is made.

Two, background technology

It is found that the today in that microelectric technique, Computer information network develop rapidly, even lightning rod has been adorned in the building outside, the power consumption equipment of indoor costliness is still usually destroyed by thunderbolt.This is because during the sky thundercloud discharge, can induction on power supply electric line produces the high voltage shock wave of thousands of volts even volts up to ten thousand, and the power consumption equipment that is connected with power line is broken.The harm that this thunderbolt causes is very wide, causes enormous economic loss and working barrier to the user.In order to prevent this thunderbolt, must install the protective device that anti-lightning induction and lightning wave are invaded additional at the house lead in place of power line and the power end of power consumption equipment.The valve-type arrester of the traditional structure that China's low voltage transmission line uses; be that the metal oxide valve block directly is connected between power line and the ground; when breaking when the valve block serious heating of electric leakage causing or by strong lightning current; tend to cause accidents such as electric power system short circuit, power failure, can not play the reliably protecting effect.

Three, summary of the invention

1, technical problem

Goal of the invention of the present utility model provides a kind of good lightning protection properties that both had, and has dual self protection type's power lightning protection module of dual security protection function again.

2, technical scheme

Dual self protection type's power lightning protection module of the present utility model is made up of pressure-sensitive valve block, fuse link, thermostat, pivoted arm, remote signalling contact, resistance, luminous tube, housing, input terminal, outlet terminal, extension spring.Wherein pressure-sensitive valve block is positioned at the middle part of housing, both sides at pressure-sensitive valve block are connected with electrode slice, surface at pressure-sensitive valve block is fixed with thermostat, the lower hinge of pivoted arm is on tumbler shaft, be connected by extension spring between the top of pivoted arm and the shell, the middle part of pivoted arm is connected with fuse link, and an end of fuse link is connected with electrode slice, and the other end is connected with outlet terminal by outlet.Implant thermostat in inside modules, two ends were received outlet terminal and input terminal respectively after thermostat was connected with luminous tube, resistance, the sequence of positions of three's series connection can be changed arbitrarily, pressure-sensitive valve block, fuse link are in series on circuit structure, one termination input terminal, other end leading-out wire terminal is after thermostat, luminous tube, resistance are in series, one termination input terminal, other end leading-out wire terminal.Be provided with the remote signalling contact in the bottom of pivoted arm and pass through two holding wires and be connected with the remote signalling terminal.On fuse link, be provided with a polygonal fusing neck hole.

3, technique effect

Advantage of the present utility model is that this module not only has good lightning protection performance, and the protection power consumption equipment is not broken; And when valve block performance degradation, leakage current increase or other reason cause that the module heating surpasses design temperature, will send light warning indication automatically, the attendant can in time be ascertained the reason fix a breakdown.When being subjected to especially big lightning wave impulse or seriously generating heat and when damaging, the fuse link action module will break away from power supply automatically, and send alarm signal and red marker indication, can not cause electric power system short circuit and power outage.Obviously, use this dual self protection type's lightning-protection module, further improved the security reliability of electric power system operation.

Five, specific embodiments

Embodiment of the present utility model is as follows:

Shell 12 is made by insulating material, and middle part in the enclosure is provided with pressure-sensitive valve block 1, and thermostat 10 places in the pole plate of pressure-sensitive valve block, and its two lead-in wire is connected to luminous tube 14 and outlet terminal 9 respectively.Draw an electrode slice 3 in a side of valve block, an end of fuse link 2 is connected on this electrode slice 3, and the other end of fuse link is connected with outlet terminal 9 by outlet 91.In order to improve the protection effect of fuse link, on fuse link 2, be provided with a square fusing neck hole 21.The lower hinge of pivoted arm 8 is in rotating shaft 81; Pivoted arm top is connected with extension spring 11, and the other end of extension spring is connected on the interior sidewall of shell, is connected with fuse link 2 at the middle part of pivoted arm.Input terminal 4 is connected with resistance 6 with pressure-sensitive valve block 1 by inlet wire 41, and resistance 6 is connected in series with luminous tube 14, thermostat 10.Pour into sealing in the last cavity volume on pressure-sensitive valve block.For the ease of observing, be provided with green plate in the upper end of pivoted arm, below green plate, be provided with a fixing red plate, the corresponding shell on these two colour table tops is provided with a fault display window 13.During normal the operation, the green plate of pivoted arm 4 is aimed at watch window, shows fault-free.On circuit structure, pressure-sensitive valve block 1, fuse link 2 are in series, one termination input terminal 4, other end leading-out wire terminal 9, after thermostat 10, luminous tube 14, resistance 6 are in series, one termination input terminal 4, other end leading-out wire terminal 9, remote signalling contact 7 connects fuse link 2, two output termination remote signalling terminals 5 of remote signalling contact 7.Aging or other insulating barrier damages and causes that leakage current increases and generates heat when pressure-sensitive valve block, and thermostat 10 actions can be sent visual alarm when arriving design temperature.This moment, the attendant should ascertain the reason, and fixed a breakdown.Alarm temperature can be selected as required, generally should not be above 100 ℃.If in servicely attacked by especially big strong lightning current, pressure-sensitive valve block 1 breakdown short circuit forms bigger short circuit current between the turnover line terminals, and fuse link 2 cuts off short circuit current to earth immediately in the quick-break of square opening place; Pivoted arm 8 is shifted under the extension spring effect, and observation panel shows red; Make the remote signalling closing of contact simultaneously, connect the remote signalling supervisory circuit.This moment, the attendant should in time change new module.
