Problems solved by technology

Such a simple outage procedure is not only unattractive, but also cannot ensure that the outage transformer is completely isolated from the power grid. If the user connects the transformer without permission, it will not only cause losses in electricity fee recovery, but may also cause personal injury or death. Hidden dangers

Embodiment 1

[0020] Special sealing for outage transformers, such as figure 1 and figure 2 As shown, it includes a hollow box body 2 and a box cover 7 covering the opening of the box body in a drawing manner.

[0021] The box body 2 is fixedly connected by four side walls and a bottom plate 8 , and has a rectangular hollow box body structure as a whole. A handle 1 is welded at one end of the length direction of the box body 2, which is convenient for carrying. The bottom plate 8 is made of insulating material, and four through holes 6 are opened on the bottom plate, and each through hole 6 is a long hole. The distance between adjacent long holes is 6-10 centimeters, the length of each long hole is 24-36 millimeters, and the width of the holes is 10-14 millimeters. Here, the length direction of the elongated hole refers to the direction along the connection line of the through hole. Preferably, both ends of the elongated hole are semicircular holes. When in use, adjust the position of...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that the box cover has a structure with a lower edge, and the four sides of the box cover are fixedly arranged to cover the lower edge of the box body, and one of the lower edges of the box body is connected with the hinge through the The corresponding outer wall of the box body is connected. The box cover is hinged with the box body through hinges. When in use, open the hinged box cover, screw in the nut of the mating contact and seal it with paint, and then buckle the box cover to seal the surface between the box cover and the box body.

Abstract

The invention discloses a sealing box special for a shutdown transformer. The sealing box comprises a hollow box body composed of side walls and an insulating base. Through holes used for being connected with secondary side contacts of the transformer in a sleeved mode are formed in the base. The sealing box further comprises a nut used for locking the contact, and a box cover movably connected with the box body is arranged on the upper portion of the box body, wherein the box cover is sealed through the surface seal after covering. The number of the through holes is four, and each through hole is a long hole extending in the through hole connecting wire direction. The distance between every two adjacent long holes is 6-10cm, the length of each long hole is 24-36mm, and the width of each hole is 10-14mm. Gaskets used for covering the through holes are arranged on the contacts in the box body in a sleeved mode. A handle is arranged at one end of the box body. The sealing box special for shutdown transformer is simple in structure, reasonable in design and convenient to carry, is in the sealing box mode and is simple and useful, and shutdown operation can be achieved conveniently. Non-staff are effectively prevented from dismantling shutdown transformer sealing wires without permission.

Description

technical field [0001] The invention relates to an auxiliary tool for power equipment, in particular to a special sealing box used during a transformer outage. Background technique [0002] In the prior art, after receiving the user's application for outage of the transformer, the electric power department will go to the site to handle the transformer outage procedure according to the user's needs. When working on site, the staff uses aluminum wires as short wires to wind the four contacts (terminal posts) on the secondary side of the transformer in sequence. Such a simple outage procedure is not only unattractive, but also cannot ensure that the outage transformer is completely isolated from the power grid. If the user connects the transformer without permission, it will not only cause losses in electricity fee recovery, but may also cause personal injury or death. hidden dangers. Contents of the invention [0003] The technical problem to be solved by the present inven...
