Abstract
The invention relates to a gap type lightning protector with a releasing device. At present, the adopted thermal explosion type lightning protector with a releasing device has the defects that the probability of misoperation is high, and a new lightning protector can not be discovered and replaced in time after the releasing device is released, thus electric equipment is in the environment without the protection of the lightning protector. The invention aims to provide the gap type lightning protector with the releasing device, which has convenient and quick installation, good protection performance and long service life. The gap type lightning protector has a structure that a lightning protector body is fixed on a bracket and an insulated supporting plate, and the releasing device and a discharge gap are fixed on the supporting plate. The invention has the effect that the lightning protector, the discharge gap and the releasing device are organically combined to form an integral structure which has convenient and quick installation. The invention solves the technical problem that when a thermal explosion type releasing device is released after operation or misoperation, if the lightning protector can not be discovered and replaced in time, the protected equipment is damaged because of no protection.
Description
Technical field
The present invention relates to a kind of gap type lightning protector with releasing device.
Prior art
In at present domestic 3KV, 6KV, 10KV, the 35KV electric power system, generally adopted heat explosion type band disconnector lightning arrester.Heat explosion type band disconnector lightning arrester is that its power frequency fault current continues to increase when utilizing lightning arrester to damage, and makes inner electric arc and the heat energy of producing of disconnector, ignites special explosive rapidly, and lightning arrester is out of service.And this heat explosion type lightning arrester, often this disconnector just begins action after through once big lightning impulse, causes lightning arrester might also not damage the operation that just logs off.So the probability of heat explosion type disconnector misoperation is than higher.Disconnector breaks away from, and can not in time find the lightning arrester that more renews, and power consumption equipment will be in the environment that does not have protection of arrester.If the superpotential words of secondary are arranged, will cause the damage of power consumption equipment.
State Intellectual Property Office's net has been announced the patent that name is called " dislodging formula band disconnector lightning arrester " on August 19th, 2009, application number: CN200820188168.X, its technical scheme is: use mounting bracket that supporting insulator is installed on the cross-arm, lightning arrester is installed among the attaching nut of top and the bottom attaching nut in, use the adjusting bolt fastening, the lightning arrester that fixes is installed in the bottom to be connected on the pedestal, the live part lead-in wire is installed on the lead-in wire connecting bolt, disconnector is installed in the lightning arrester bottom and connects the contact below or be installed in supporting insulator bottom connection pedestal below, when lightning arrester breaks down, disconnector is thrown off automatically, and lightning arrester is out of service.
In sum, find easily, can not make system's generation single phase ground fault, can not play safe protection power consumption equipment though band disconnector lightning arrester has solved the fault point.Even also there is not disconnector to break away from present, lightning arrester can also work on, and can also play due protection to power consumption equipment, till the lightning arrester that more renews, and has the fault lightning arrester also to find easily.
State Intellectual Property Office's net discloses a kind of name on September 28th, 2006 and has been called " external series gap lightning arrester ", application number: CN200610047947.3, its structure is to be set in that series connection is provided with the external series gap electrode that constitutes the discharge external series gap with lightning arrester body on the axis body of lightning arrester body.
State Intellectual Property Office's net discloses a kind of name on September 28th, 2006 and has been called " spark gap arrestor ", application number: CN200580003891.5, structure is in the lightning arrester of enclosing structure, do not rely on the voltage drop of arc current by increase, prevent because the scratch start again that the supply voltage of lightning current after flowing through causes, thereby realize not having the spark gap arrestor of continuous current.In taking in the cylindrical metal housing of spark gap, as muffler plate configuration and the circular cone or the concentric a plurality of magnetic beckets of cylindric electrode that constitute spark gap.The muffler plate of the electric arc guiding periphery that will produce owing to flowing through of lightning current, thereby the scratch start again that utilizes the supply voltage after the arc voltage that produces on the muffler plate two sides prevents to flow through owing to lightning current to cause.But this structure (1) is analyzed from the infrastructure product structure, and its gap is provided in a side of lightning arrester inside.(2) analyze from interstitial structure, be provided with a plurality of magnetic beckets in the spark gap, structure is comparatively complicated.
Summary of the invention
