Description
Technical Field
The utility model belongs to the technical field of the leaking stoppage instrument, concretely relates to russian million generator goes out line sleeve pipe and leaks leaking stoppage instrument.
Background
A certain type of generator is manufactured for Russian electric power factory, and adopts water hydrogen cooling mode, namely stator winding water cooling, iron core and end structural member hydrogen surface cooling, and the rotor adopts the air gap cooling mode of getting gas. The three-phase outgoing line is composed of a parallel connection ring, a main lead, a flexible connection, a porcelain sleeve and a hollow conducting rod, and cooling water is introduced into the conducting rod for cooling. In order to prevent hydrogen leakage, the outgoing line sleeve and the shell as well as the conducting rod are sealed by rubber sealing gaskets. After the annual overhaul of the generator is completed, when the unit is subjected to a whole airtight test in a hydrogen state, the hydrogen leaks from the sleeve and the conducting rod due to the thermal expansion and cold contraction of the sealing gasket and aging influence, so that the safety of the unit is influenced.
Hydrogen is a flammable and explosive gas, and explosion accidents easily occur when a large amount of hydrogen is leaked. In order to ensure the safety of personnel and equipment and ensure the stable operation of the unit, when the hydrogen leakage defect occurs, the blockage is carried out by adopting a rapid and reliable processing mode as far as possible.
Under normal conditions, if hydrogen leaks from sleeve pipe and conducting rod sealing position, need demolish the flexible coupling top staple bolt of being qualified for the next round of competitions, work load is great, and the space is narrow, and operational environment is relatively poor, occupies the thread time. In order to eliminate defects, the safe and stable operation of the unit is ensured, and meanwhile, the leakage part is fastened on the premise of not removing the hoop, so that the blocking is completed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a russian million generator outlet sleeve leaks leaking stoppage instrument, when carrying out complete machine airtight test, when going out the line sleeve and being qualified for the next round of competitions with the conducting rod and leaking, under the prerequisite of not demolising the staple bolt, fasten the position of leaking, accomplish the shutoff, guarantee unit safety, steady operation and ensure personnel's safety.
The utility model adopts the technical proposal that:
a leakage plugging tool for leakage of a wire outlet sleeve of a Russian million-generation generator comprises a straight line section, a circular arc section and a fastening point; the straight line section is welded with the arc section, and the fastening point is welded on the upper surface of the arc section.
The straight line section, the circular arc section and the fastening point are made of stainless steel.
The length of the straight line section is 280mm-285mm, the diameter of the circular arc section is 135mm, and the height of the fastening point is 7 mm.
The arc segment is installed between the conducting rod and the fastening flange.
The fastening points are inserted into the fabrication holes of the fastening flange.
Compared with the prior art, the beneficial effects of the utility model reside in that:
(1) the utility model provides a leakage plugging tool for the outlet sleeve of a Russian million-generation generator, which has simple structure and convenient operation;
(2) the utility model provides a leakage plugging tool for a wire outlet sleeve of a Russian million-made generator, which is used for fastening a leakage part on the premise of not removing a hoop to complete plugging and provide working efficiency when a complete machine airtight test is carried out and the wire outlet sleeve and a conducting rod are subjected to wire outlet leakage;
(3) the utility model provides a million generators in Russia outlet sleeve leaks leaking stoppage instrument can improve unit operating stability and economic nature, ensures personnel's safety.
