Abstract
The utility model provides an arrester for a combined serial clearance type disconnecting mechanism. An electrode at one end of a valve plate arrester body is fixedly assembled with the clearance type disconnecting mechanism; the disconnecting mechanism comprises an insulating bracket; the insulating bracket consists of an assembling seat and an upper shelf plate, wherein the assembling seat is wholly provided with an insulating stanchion; the upper shelf plate is fixed at the external end of the insulating stanchion; and two spherical electrodes with relative discharging spacing are fixed on the assembling seat and the upper shelf plate respectively, wherein the upper spherical electrode is a stainless steel spherical bolt with the spherical diameter being less than the lower spherical electrode that is prepared by easily fused metal and has a large spherical surface. In the technical scheme, the electrode having the large spherical surface and being prepared by the easily fused metal is used for finishing the disconnecting function of the damaged arrester, so that the manufacturing cost is reduced without influencing the technical function, and simultaneously the fixed connecting part of the disconnecting mechanism and the arrester body has higher mechanical strength, higher torsional strength and higher bending strength, therefore, the arrester has consistent strength requirement with a composite needle type insulator, thus having good generality and interchangeability.
Description
Technical field
The utility model relates to the lightning protection device that is assemblied in the high-tension distributing line.
Background technology
Zero-clearance zinc oxide lightning arrester is still the lightning-arrest product of main flow in the high-tension distributing line.The moment of lightning-arrest fault and the technical purpose that power network breaks away from appear for accomplishing at lightning arrester; Thereby ensure the power network safe operation; Be the basis with the lightning arrester structure; Be series at lightning arrester one end and be provided with the hot melten type disconnector by installing rack, make the lightning arrester and the power network that have damaged break away from Chinese patent automatically with the meltdown mode: the patent No. is 03213798.2, " alternating current external gap type breaks away from lightning arrester automatically " technical scheme just realizes this technical functionality.Be connected on to fixedly mount on lightning arrester body one termination electrode and be provided with the external series gap disconnector; Disconnector is made up of two relative big spheres of spacing, and two radius tip electrodes are by special fusible alloy material manufacture, and the cost cost is higher; Damage in case valve block is lightning-arrest, two big radius tip electrodes can melt down into fine granularity.This structure assembling parts is many and complicated, also therefore can increase many assembly operation steps, and the disconnector installing rack is made up of the some insulated column three big parts of upper and lower installation panel and middle part; Member is more, and insulated column is processed for the DMC material, from structure and material two aspects; The technical problem that exists is that terminals tolerate mechanical bent load-bearing capacity deficiency; Only reach 400N, if with its integral body as pin insulator, then on load intensity, have bigger technological gap.
Summary of the invention
The technological invention purpose of the utility model is to provide a kind of cost to reduce, structure is simplified, improve the lightning arrester that wiring tolerates the combined serial clearance-type releasing mechanism of mechanical strength simultaneously.The lightning arrester technical scheme of the combined serial clearance-type releasing mechanism that the utility model provides; Its major technique content is: a kind of lightning arrester of combined serial clearance-type releasing mechanism; Valve block arrester body one termination electrode fixation group is equipped with the clearance-type releasing mechanism; Releasing mechanism is made up of insulating support assembling, and insulating support is shaped on insulation column by integral body mount pad constitutes with the last frame plate that is fixed on the insulation column outer end, two radius tip electrodes distinguish upper and lower relative fixed mount pad, on the frame plate; Wherein going up radius tip electrode is the stainless steel sphere bolt of sphere diameter less than the big sphere lower peripheral surface of fusible metal system electrode, and the sphere bolt is as the wiring external electrode.
The lightning arrester technical scheme of the disclosed combined serial clearance-type of the utility model releasing mechanism; It is the big radius tip electrode that fusible metal is processed that two radius tip electrodes in its releasing mechanism have only one of them; On the basis of influence technique function not, reduce the cost cost; Another radius tip electrode adopts the sphere bolt arrangement simultaneously, and connector assembly reduces significantly; In addition; Releasing mechanism is fixedly connected part with lightning arrester body mechanical strength and antitorque, flexural strength have all obtained substantial raising; On size with compound pin insulator near; On performance, also reached the requirement of strength with compound pin insulator, both have good versatility and interchangeability.
