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, 35KV electric power system, generally adopted heat explosion type band disconnector lightning arrester.Heat explosion type band disconnector lightning arrester is that while utilizing lightning arrester to damage, its power frequency fault current continues to increase, and makes inner electric arc and the heat energy of producing of disconnector, ignites rapidly special explosive, and lightning arrester is out of service.And this heat explosion type lightning arrester, often after the lightning impulse through once large, this disconnector just starts action, causes lightning arrester likely also not damage the operation that just logs off.So the probability of heat-explosion type disconnector misoperation is higher.Disconnector departs from, and can not find in time the lightning arrester that more renews, and power consumption equipment will be in the environment that there is no protection of arrester.If there is secondary overvoltage, will cause the damage of power consumption equipment.
State Intellectual Property Office's net has been announced the patent that name is called " hanging lightning arrestor with separator " on August 1st 9,2009, application number: CN200820188168.X, its technical scheme is: use mounting bracket that supporting insulator is arranged on cross-arm, lightning arrester is arranged in the attaching nut of top and bottom attaching nut in, use adjusting bolt fixing fastening, the lightning arrester fixing is arranged on to bottom to be connected on pedestal, live part lead-in wire is arranged on lead-in wire connecting bolt, disconnector is arranged on lightning arrester bottom and connects contact below or be arranged on supporting insulator bottom connection pedestal below, when lightning arrester breaks down, disconnector is thrown off automatically, lightning arrester is out of service.
In sum, although band disconnector lightning arrester has solved fault point, easily find, can not make system generation single phase ground fault, to power consumption equipment, can not play safe protection.Even if also do not have at present disconnector to depart from, lightning arrester can also work on, and to power consumption equipment, can also play due protection, until the lightning arrester more renewing, and have fault lightning arrester also easily to find.
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 series connection on the axis body of lightning arrester body to be provided with the external series gap electrode that forms electric discharge external series gap with 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 enclosing the lightning arrester of structure, by increase, do not rely on the voltage drop of arc current, prevent the scratch start again causing due to the supply voltage of lightning current after flowing through, thereby realize the spark gap arrestor that there is no continuous current.In taking in the cylindrical metal housing of spark gap, as circular cone or the concentric a plurality of magnetic beckets of cylindric electrode of muffler plate configuration and formation spark gap.By the muffler plate of the electric arc guiding periphery producing due to flowing through of lightning current, thus the scratch start again that the supply voltage after utilizing the arc voltage producing on muffler plate two sides to prevent from flowing through due to lightning current causes.But this structure (1) is analyzed from infrastructure product structure, and its gap is provided in a side of lightning arrester inside.(2) from interstitial structure, analyze, be provided with a plurality of magnetic beckets in spark gap, structure is comparatively complicated.
Summary of the invention
The present invention seeks to develop a kind of gap type lightning protector with releasing device.The present invention is for solving problems of the prior art, as can not be reliably carried out safe protection, complex structure etc. to power consumption equipment; Do not affecting under the condition that lightning arrester works on, can pinpoint the problems again more renews in time lightning arrester and provides a kind of simple in structure for realizing object simultaneously, uses safety, gap type lightning protector with releasing device easily.
