Abstract
The invention relates to a hard insulating shield cover specialized for 35kV live operation. The hard insulating shield cover comprises two shield units which are symmetrical in shape. The two shield units are oppositely arranged. Each shield unit is formed by two epoxy resin bodies and one nylon framework. The upper ends of the two epoxy resin bodies are connected by the nylon framework. The front ends, the rear ends and the lower ends of the two epoxy resin bodies have an open structure. An installing area used for installation of an iron tower frame in a penetrating way is formed between the two epoxy resin bodies and the nylon framework. A handle is installed on the nylon framework. An open groove is manufactured at the front end of the nylon framework. The invention provides the hard insulating shield cover specialized for 35kV live operation through design, and the hard insulating shield cover is convenient for operation of live operation personnel and is safe and reliable. After insulating shielding is performed on a live part by live operation personnel, a closer iron tower is shielded by using the hard insulating shield cover so that reliable insulating protection is provided to the live operation personnel in operation.
Description
Technical field
The present invention relates to live line working professional skill field, especially a kind of 35kV live line working dedicated hard insulated shielding cover.
Background technology
At present, carry out in the unloaded lead-in wire work of the charged disconnecting of insulating gloves method adopting the 35kV overhead transmission line of steel tower erection, live line working personnel are potential range steel tower close together when the operation of disconnecting lead-in wire, live line working personnel and electrified body and earth electrode can not meet minimum safe distance, there is potential safety hazard in operation process, worker safety can not get ensureing.
Summary of the invention
The object of the present invention is to provide a kind of easy to use, be easy to install, practical, can eliminate safe hidden trouble, the 35kV live line working dedicated hard insulated shielding cover of safeguard work personal security.
The object of the invention is to be realized by following technological means:
A kind of 35kV live line working dedicated hard insulated shielding cover, it is characterized in that: the shielding cell comprising two symmetrical shape, these two shielding cells are oppositely arranged, each shielding cell is formed by two body of epoxy resin and a polyamide skeleton, the upper end of two body of epoxy resin is connected by polyamide skeleton, the front end of two body of epoxy resin, rear end and lower end are unenclosed construction, two installation regions formed between body of epoxy resin and polyamide skeleton for installing steel towers; Polyamide skeleton is installed a handles, and a fluting is made in the front end of this polyamide skeleton.
And, a draw-in groove is made in the front end of one of them body of epoxy resin of described each shielding cell, this draw-in groove is consistent with the direction that polyamide skeleton is slotted, and the body of epoxy resin below this draw-in groove is made a large recess, and a little recess is made in the bottom of another body of epoxy resin.
And one or more through hole is made in the lower end of described body of epoxy resin, two shielding cells are connected by the pin be arranged in through hole.
Advantage of the present invention and good effect are:
1, this insulated shielding cover is made up of two shielding cells of near symmetrical, and it overlaps on steel tower mutually, operating personnel and earth electrode is effectively isolated, and forms the insulation protection to live line working personnel, eliminates potential safety hazard.
2, this insulated shielding cover is made up of nylon and epoxide resin material, and nylon is higher due to mechanical performance, is used for making skeleton of the present invention; Epoxy resin lighter weight, as the main body of mask, they all have good insulation property, and therefore this mask insulation effect is good, the safety of energy safeguard work personnel.
3, the present invention is a kind of simple to operate, safe and reliable, with low cost, remarkably productive, the 35kV live line working special isolation being applicable to applying covers apparatus, this mask is the 35kV overhead transmission line live line working design aiming at steel tower erection, effectively can prevent live line working personnel operation danger that electric discharge causes the person to get an electric shock apart from earth electrode is too near on alive circuit, substantially increase operating efficiency and fail safe, solve live line working personnel potential range steel tower close together when the operation of disconnecting lead-in wire, live line working personnel and electrified body can not meet the huge hidden danger of minimum safe distance, can effectively be applied in the live line working of 35kV insulating gloves method.

Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of 35kV live line working dedicated hard insulated shielding cover, comprise the shielding cell (A and B in Fig. 1) of two symmetrical shape, these two shielding cells are oppositely arranged.Each shielding cell is formed by two body of epoxy resin 1 and a polyamide skeleton 7, the upper end of two body of epoxy resin is connected by polyamide skeleton, the front end of two body of epoxy resin, rear end and lower end are unenclosed construction, two installation regions formed between body of epoxy resin and polyamide skeleton for installing steel towers.
Polyamide skeleton is installed a handles 2, and according to iron tower structure, in order to the present invention can be enable to be installed to suitable position, a fluting 8 is made in the front end of this polyamide skeleton; A draw-in groove 4 is made in the front end of one of them body of epoxy resin of each shielding cell, and this draw-in groove is consistent with the direction that polyamide skeleton is slotted; Body of epoxy resin below draw-in groove is made a large recess 5; A little recess 6 is made in the bottom of another body of epoxy resin.In addition, also make one or more through hole 3 in the lower end of body of epoxy resin, after two shielding cell overlaps, pin 9 is inserted in through hole, enable the present invention be fixed on steel tower, prevent come off (as shown in Figure 5).
Using method of the present invention is:
The a complete set of insulating protection apparatus of live line working persons wear handles aerial lift device with insulated arm to correct position, and after the insulation carrying out electrified body is covered, after the license of work director, this rigid insulation mask is installed in steel tower and insulator the most nearby by live line working personnel.During operation, live line working personnel only need the handle of hand-held mask, the A of insulated shielding cover, part B are installed in successively on steel tower respectively, plug pin.
