Abstract
The utility model relates to the technical field of power transmission line equipment, in particular to a pin type insulator. In the prior art, a high-voltage power transmission wire is binded on the porcelain insulating body of the pin type insulator by a binding rope. When the pin type insulator is in practical use, since the porcelain insulating body is affected by lightning strike, wind and the like, the binding rope is often loosened or broken to cause accidents such as 'flying wire' (i.e. falling off of the power transmission wire) and grounded short-circuiting of the wire, which can lead to power failure, equipment damage and the like. The technical scheme of the utility model is as follows: the upper part of a porcelain insulating body is provided with a wire groove, a wire-holding plate is assembled on fixed bolts at both sides of the wireway, and a supporting bolt is mounted at the center of the bottom of the porcelain insulating body. The utility model has the advantages that: the structure is simple and reasonable, the operation is easy, the time of aerial work conducted by workers is shortened, the working efficiency is increased, and accidents, such as 'flying wire' and short-circuiting, which are caused by the loosening or breaking of the binding rope due to lightning strike, aging and the like, are prevented.
Description
Technical field
The utility model relates to the transmission line equipment technical field, specifically a kind of pin insulator.
Background technology
Pin insulator is a kind of electric elements commonly used in the electric power system, is usually used in supporting and fixing cord in the high and low pressure transmission line.Existing pin insulator is to have annular wire casing in insulating ceramic upper end one around porcelain body, and high voltage transmission line is walked around the annular wire casing of insulating ceramic, and ties up by wiring and to be fixed on the porcelain body.In actual use, because porcelain body influences by thunderbolt, wind etc., often occur that wiring is loosening, rupturing causes accidents such as lead " fly line " (being that transmission pressure comes off), ground short circuit, causes power failure, device damage etc.
Summary of the invention
The purpose of this utility model provides a kind of pin insulator, has solved pin insulator in actual use owing to influenced by thunderbolt, wind etc., often occurs that wiring is loosening, rupturing causes accidents such as transmission pressure comes off, ground short circuit.
The technical solution of the utility model is: comprise insulating ceramic, supporting screw; Also form by set bolt, wireplint, collision mat; Insulating ceramic top has wire casing, and respectively there is one to two bolt connecting hole the wire casing both sides, by screw thread or adhesive a set bolt is installed respectively in each bolt connecting hole; Be equipped with wireplint on the set bolt; Be equipped with collision mat between wireplint and the insulating ceramic; The insulating ceramic bottom center has pit, and the screw rod connecting hole is arranged in the pit, by screw thread or adhesive supporting screw is installed in the screw rod connecting hole.
The utility model is fixed on pin insulator on the cross-arm of bar, tower by supporting screw, and transmission pressure snaps in the wire casing of insulating ceramic, and is fixedly clamped by wireplint.
The utility model has the advantages that: simple and reasonable, easy and simple to handle, reduced time of staff's aerial work, improved mechanical strength, avoided because thunderbolt, wiring pine, disconnected " fly line " short circuit ground fault that causes of causing such as aging.
