Background technology
The insulated overhead line overwhelming majority suffers indirect lightning strike; when the lightning overvoltage flashover; because overvoltage protection device is in parallel with line insulator; lightning current causes that high potential makes the series gap action of circuit fixed interval (FI) overvoltage protection device; reduced the potential difference between tower arm and lead; guarantee no longer flashover of insulator; thereby avoided the line tripping power failure; in order to guarantee the operate as normal of circuit fixed interval (FI) overvoltage protection device; must guarantee outer discharging gap distance within the limits prescribed, and can guarantee that circuit fixed interval (FI) overvoltage protection device installs and fixes reliably for a long time.Have following problem in the existing design: common or conventional installation gold utensil is being installed with in service; because the reciprocating motion effect concussion of the long-term wind-engaging pendulum of 10kV insulated conductor; the gold utensil landing appears repeatedly or whole circuit fixed interval (FI) overvoltage protection device drops; cause potential safety hazard, the insulated overhead line thunder resisting equipment is circuit fixed interval (FI) overvoltage protection device cisco unity malfunction.
And existing installation gold utensil is designed to horizontal direction on the market at present, and snowing heavily at changeable harsh climate environment now particularly forms accumulated snow in winter in the environment easily; Along with the minimizing of trees quantity, various birds also can be chosen in takes branch and does nest on the gold utensil, thereby reduces equipment outer insulation, reduces the reliability of equipment electric property.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the installation gold utensil of a kind of circuit fixed interval (FI) overvoltage protection device is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
The installation gold utensil of a kind of circuit fixed interval (FI) overvoltage protection device; comprise insulator end gold utensil, vertically connect gold utensil and lightning arrester end gold utensil; described insulator end gold utensil is for L shaped; it vertically has electrode mounting hole in the part middle part; its top planar section has the arc opening slot; described lightning arrester end gold utensil is for L shaped; its planar section center, top has installing hole; the top plane end has location hole, and described insulator end gold utensil vertically part is vertically partly fixing by vertically being connected the gold utensil welding with lightning arrester end gold utensil.
And described to fall L shaped insulator end gold utensil be 200～400mm height, and 25～80mm is wide, the iron metalwork that 3～8mm is thick, and the diameter of the arc opening slot of its top planar section is 10～25mm.
And described to fall L shaped lightning arrester end gold utensil be 30～100mm height, and 25～80mm is wide, the iron metalwork that 3～8mm is thick, and the installing hole diameter of its top planar section is 8～17mm, the location hole diameter is 3～7mm.
Advantage of the present utility model and good effect are:
1, the utility model is simple in structure, and technology reliably has very high practicality and feasibility.
2, the utility model improvement expenses is low, possesses the possibility that large tracts of land is promoted.
Although related device self cost of 3 the utility model is not high, its universal use can increase the safety operation level of overhead transmission line greatly, direct losses and the indirect loss of avoiding gold utensil landing, bird pest even accumulated snow etc. to cause distribution line to have a power failure.
