Abstract
The utility model discloses a protective cover special for a transformer substation QK handle. Two symmetric side plates are hinged on two sides of a plastic panel through hinges, and bar-shaped magnets are respectively fixedly arranged on the plate surfaces of the outer sides of the two side plates. The length direction of the bar-shaped magnets is parallel to the axial line direction of the hinges. Polarities of opposite ends of the two bar-shaped magnets are opposite. When the protective cover is used for carrying out maintenance works in a transformer substation, the QK handle of operation equipment circuit breaker is covered for protecting the operation equipment and warning a maintainer so that the circuit breaker is prevented from being switched on or off by mistake, and potential safety hazards in a maintenance process are eliminated. The protective cover is convenient to use and avoids the waste.
Description
Technical field:
The utility model relates to a kind of QK of transformer station handle Special protecting hood.
Background technology:
The QK handle is one of components and parts that frequency of utilization is higher in the transformer station, no matter be that operating personnel carry out grid switching operation, or the maintainer all need pass through QK handle deciliter respective circuit breakers in the service work process.The situation that all has several line-breaker measure and control devices and QK handle group screen in most of transformer station, when a certain circuit breaker of maintenance, because need of work, need repeatedly use QK handle deciliter maintenance circuit breaker, and the interior Other related equipment of screen is all in running status, mistake roping row circuit breaker very easily occuring cause the mistakenly stop electricity, has serious potential safety hazard.At present the maintenance personnel of teams and groups generally adopt the method that red adhesive plaster is bonded on the operational outfit QK handle when implementing the secondary safety measure, in order to remind oneself, prevent misoperation.But cause panel comparatively chaotic because the rubberized fabric adhere method lacks unified implementation criteria, and after recovering the secondary safety measure behind the end-of-job, the adhesive plaster of stickup can't carry out the secondary utilization, has caused the waste of resource.
Summary of the invention:
For overcoming the defective of prior art; the purpose of this utility model is to provide a kind of protective cover that reuses; when being used in the transformer station service work; cover operational outfit circuit breaker Q K handle; to protect operational outfit and to warn the maintainer; prevent mistake deciliter circuit breaker, eliminate the potential safety hazard in the maintenance process.Not only easy to use and stopped before wasting phenomenon.
The utility model technical solution problem adopts following technical scheme:
The QK(of transformer station control switch) handle Special protecting hood, it comprises:
Panel is hinged with the side plate of two symmetries by hinge on the both sides of described panel;
On the outer panel face of described two blocks of side plates, be installed with respectively bar magnet.
The length direction of described bar magnet is parallel with the axis direction of described hinge.
The polarity that two described bar magnets are held in opposite directions is opposite each other.
The width sum of two blocks of described side plates equals the width of described panel.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model protective cover mainly is comprised of three kinds of materials: plastics, magnet, metal hinge, open it during use, because the suction between magnet and the observing and controlling panel, can firmly be adsorbed on the panel QK handle is covered fully, easy to use, and improved operating efficiency.Panel surface is red, and is printed on yellow " operational outfit " printed words, can effectively play warning function, guarantees that the service work personnel can malfunction operational outfit QK handle.After service work finishes, it is taken from the observing and controlling screen, owing to being provided with hinge, adding the rational size design of both sides plastic plate (both sides side plate width dimensions addition equals the front panel width dimensions) can be folding with it, both sides magnet polarity is respectively N, the S utmost point, firm after guaranteeing to fold, can be not loose, but inserter case, because main material is plastics, so weight is lighter, the easy access personnel carry and use.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 panel, 2 hinges, 3 side plates, 4 magnet.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1, the QK(of the transformer station control switch of the present embodiment) the handle Special protecting hood, it comprises:
Panel 1 is hinged with the side plate 3 of two symmetries by hinge 2 on the both sides of panel 1; And on the outer panel face of two blocks of side plates 3, be installed with respectively bar magnet 4.
In specifically arranging, two blocks of side plates 3 are hinged on the both sides side of the Width of panel 1, and the width sum of two blocks of side plates 3 equals the width of panel 1, guarantee two blocks of side plates folding after and panel substantially be equal to size.Article two, the length direction of strip magnet is parallel with the axis direction of hinge, and the polarity that two bar magnets are held in opposite directions is opposite each other, like this after two blocks of side plates are folding in opposite directions end can be attached together and can not scatter.
In the implementation, panel 1 and two blocks of side plates 3 adopt plastic production, and weight is lighter, is easy to carry.Panel is for redness and be printed on " operational outfit " printed words with yellow material on panel, can effectively play warning function, guarantees that the service work personnel can malfunction operational outfit QK handle.
