Abstract
The utility model discloses a shield for safety precaution of relay protection equipment in a substation. The shield comprises a rotary reel capable of swinging positively and reversely, a fixing groove allowing the rotary reel to be placed and rotate freely therein, a transparent film reeled on the rotary reel, and two telescopic rods or expansion plates arranged at two ends of the fixing groove and extending in the extending direction of the film, wherein the head end of the film is fixed at the stretching ends of the telescopic rods or the expansion plates and can retract along with the telescopic rods or the expansion plates; and adsorption devices are arranged at the lower parts of the telescopic rods or the expansion plates. The utility model has the advantages that the shield adopts a telescopic structure, is made of a transparent and light-duty material, can be absorbed on a screening cabinet and can not drop off easily; the problems of cumbersome and incomplete secondary safety precautions and the like are solved; and the shield is particularly applied to safety precaution arrangement for on-screen multiple protection with partial maintenance operation, and can not influence daily inspection and the normal operation of a device.
Description
Technical field
The utility model relates to a kind of live line working safety protective tools, particularly a kind of substation relay protection device safety measure protective cover.
Background technology
In recent years, it is of common occurrence that accidents such as relaying protection personnel mistake is bumped, mis-wired take place, but the safety prevention measure method for arranging during the substation relay protection device maintenance is single, just simply usually hangs the red cloth curtain or paste red adhesive tape.This method can increase safety measure and arrange the time, and easily causes accidents such as personnel's mistake is bumped, mis-wired.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part; and provide a kind of light, good operation performance; can provide the general safety protection for the secondary device service work; the layout of safety measure when being convenient to the secondary device maintenance improves the anti-substation relay protection device safety measure protective cover of " three mistakes " level of relaying protection personnel.
A kind of substation relay protection device safety measure protective cover; its structural feature is: comprising can positive and negative revolution spool; be used to lay the holddown groove that positive and negative revolution spool also can allow positive and negative revolution spool freely rotate within it; be wound in the transparent membrane on the positive and negative revolution spool; be arranged at the holddown groove two ends and extend 2 expansion links or the expansion plate of arranging along the direction of extension of film; described expansion link or expansion plate can be done as required along the film direction of extension and stretch or contract and move; the head end of film is fixed in the stretching end of expansion link or expansion plate and can follows expansion link or expansion plate is done stretching motion, is provided with adsorbent equipment in the bottom of expansion link or expansion plate.
Substation relay protection device safety measure protective cover of the present utility model; because the top layer face shield adopts transparent membrane to constitute; transparent insulation does not influence normal tour and equipment operation; the width of protective cover can be regulated by the expansion link or the expansion plate that are arranged at the holddown groove two side ends as required; when carrying out width adjustment; the expansion link of motion or expansion plate drive the film that is fixed in the end that stretches and move together; film further follows expansion link again under the effect of revolution spool or expansion plate is done stretching motion; utilize the adsorbent equipment that is arranged at expansion link or expansion plate bottom entire equipment can be adsorbed on the relay protection device screen cashier's office in a shop simultaneously; difficult drop-off satisfies the requirement of the safety prevention measure of relay protection device.When needs are packed up this substation relay protection device safety measure protective cover, only need allow the revolution spool get final product along backward rotation.
When arranging protective relaying device panel class safety measure, protective cover is stretched to required width, be positioned over and overhaul on the protective device or diverter switch of protective device with other operations of screen, protective cover will be adsorbed on the device top of operation automatically.Effectively prevent maintainer's malfunction running protection device, this protective cover can be arranged in protective device pressing plate brace top equally, prevents to bump by mistake.
The structure that the revolution spool of positive and negative gyration is made in the energy realization has much several forms that following applicant provides:
A kind ofly be: spool is linked to each other with motor, utilize the driven by motor spool to do reversed turning.
The backrush axle of this structure drives when being stretched by the expansion link that is positioned at the holddown groove two ends or expansion plate when being used as extensional motion and stretches, and when needs turn round, utilizes driven by motor to turn round.
Second kind is: spool is provided with handle apparatus, by manually shaking the film return that the handle realization will launch.
The third is: spool is provided with torsion spring, utilizes the restoring force of torsion spring to make the film return of stretching.
Described adsorbent equipment or be the magnetic adsorbent equipment, or be the sucked type adsorbent equipment.
Described expansion link or expansion plate are for to be made of light material.
Adopt light material can alleviate the weight of whole protective roof, be convenient to absorption and use.
Described expansion link or expansion plate are served as reasons two or more, and rod member of intussusception or plate body constitute layer by layer, perhaps will adopt chute and tenon to be connected between two rod members or the plate body, utilize the slip of tenon in chute to realize that two rod members or plate body do relative motion, perhaps will adopt slideway and roller to be connected between two rod members or the plate body.
In sum, the following compared to existing technology advantage of the utility model:
Transforming plant protecting device safety measure protective cover of the present utility model adopts Collapsible structure, and selects transparent, light-duty material for use, and can be adsorbed on screen cashier's office in a shop, difficult drop-off.Because of These characteristics; the relaying protection safty shield has solved problems such as the secondary safety measure is loaded down with trivial details, imperfection; safety measure when especially only part has service work with the many cover protections of screen is arranged; and do not influence daily tour and install self normal operation, promotion prospect and the actual meaning of using are widely arranged in electric power system.
