Pressurized leakage-plugging device for hydrogen cooling generator

Abstract

The invention discloses a pressurized leakage-plugging device for a hydrogen cooling generator, comprising a leakage-plugging port, a fitting box, a reinforcing device, a casing, and an injection port, wherein the casing is inlaid with the fitting box, which is provided on an inner surface of the casing and communicates with the injection port, the injection port is provided on a side surface of the casing, the leakage-plugging port is provided on an outer surface of the fitting box, the reinforcing device is mounted on the upper side and lower side of the casing and is composed of a pulling device, a reset mechanism, a reciprocating transmission device, a lifting device, a tightening device and a tensioning device. The top of the pulling device is in movable contact with the reciprocatingtransmission device, and the reciprocating transmission device is connected with the reset mechanism. The pressurized leakage-plugging device for a hydrogen cooling generator has the beneficial effects that two symmetrically designed reinforcing devices make leakage-plugging and fixing effect better, no extra mounting steps are required when fixing the device, only fixing a fixing hook to a supporting point and then pulling a tab for tightening up and fixing, it is labor-saving when pulling, and the winding wheel is capable of preventing reversing of itself, the operation is convenient and fast, and the work efficiency is improved.

Description

Technical field [0001] The invention relates to the field of generator leakage plugging devices, in particular to a hydrogen cooling generator leak plugging device under pressure. Background technique [0002] In the operation of power plant equipment, generator hydrogen leakage is a kind of equipment defect that often occurs. The main hazards are: 1. Excessive hydrogen humidity or water or oil entering the generator will damage the stator and rotor winding insulation of the generator. Causes interphase or ground short-circuit accidents; 2. Excessive hydrogen consumption, frequent hydrogen replenishment operations, high operating costs; 3. The generator system may catch fire or explode, causing serious damage to the equipment. When the hydrogen leakage rate of the generator reaches a certain value and the hydrogen pressure cannot be guaranteed, the generator will be stopped immediately according to the operation requirements, which will affect the stable operation of the generato...

Problems solved by technology

[0003] At present, when the pressure plugging device is used, it needs to apply and adjust external force through channel steel, bolts, and jacks. There are many installation parts, which prolongs the working time and reduces the work efficiency. It is impossible to quickly and conveniently plug the leak.
