Problems solved by technology

The label on the lead seal block is unique. Once the lead seal is properly sealed, it cannot be opened without authorization, and the damaged lead seal cannot be reused.
The simple lead seal uses the lead seal wire to wrap around the terminal. This fixing method is not firm and the lead seal wire is easy to fall off
Simple lead seal wire is too thin, easy to corrode and broken by external force

Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0015] A sealing device for a suspended transformer, including two boxes, two lead seals and a soft metal wire, the box is a square box composed of four sides, including a top surface 1, a main surface 3, two Side 2, a top hole 4 is opened at the center of the top surface 1 of the box body, and the top hole 4 cooperates with the terminal post 8 of the transformer. The soft metal wire 7 is fixedly connected with the two boxes, and the two ends of the soft metal wire 7 can be inserted into the wire holes 6 of the two box bodies respectively, and then welded or connected by screws, so that the soft metal wire is fixed inside the box body. Soft metal wire 7 outsides can also be put on red hose.

[0016] During installation, the lead sealing wire binds the insulating straight bottle 9, and the two boxes are set on the two insulating straight bottles 9 and the terminal pos...

Abstract

The invention relates to a sealing device for suspending transformers, which is used for sealing the suspended transformers in the power supply system of the electric power industry. The device is composed of a box body, a soft metal wire and a lead seal, the lead seal wire is fixed on the transformer insulating straight bottle, and the box body passes through the transformer terminal. The present invention can make it more secure when sealing the suspended transformer. It solves the problems that the lead sealing wire is easy to break and the seal mark is not obvious, and improves the reliability of the lead seal.

Description

technical field [0001] The invention relates to a device for sealing suspended transformers in a power supply system of the electric power industry. Background technique [0002] When the power supply department suspends the service of the transformer, it needs to mark it with the transformer sealer. At present, when the transformer is sealed up, several terminal posts of the transformer are wrapped with lead sealing wires and then fixed with lead blocks. The terminal posts are located on the insulating straight bottle and the high-voltage bushing of the transformer. The device used to seal the transformer is a simple lead seal, which is composed of exposed lead seal wire and lead seal block. When in use, wrap the exposed lead-sealing wires on the terminals of each phase of the transformer, and fix and seal them with lead-sealing blocks. The label on the lead seal block is unique. Once the lead seal is properly sealed, it cannot be opened without authorization, and the dam...
