Abstract
The invention relates to a lifting seat explosion-proof device of a flexible direct current converter transformer and a using method thereof, belonging to the field of transformer equipment manufacturing. The technical scheme is as follows: including net side lift seat (1) and explosion-proof system, explosion-proof system includes pressure release (2) and bleeder line (3), and pressure release (2) link firmly in net side lift seat (1), and inside oil duct and the inside intercommunication of net side lift seat, bleeder line one end is passed through the overflow valve and is risen the seat with the net side and link firmly, and the bleeder line other end extends to the accident and puts the oil bath. When the transformer network side sleeve and the network side lead wire have faults, a large amount of gas is generated suddenly, and the local stress and deformation of the network side lifting seat are overlarge, so that the internal oil pressure is increased, and when the network side lifting seat explodes, the internal high-pressure oil can be timely decompressed, thereby avoiding explosion or preventing the accident from further expanding, reducing the linkage loss, and avoiding the economic loss and the social influence caused by large-area power failure due to the explosion accident of the network side lifting seat.
Description
Technical Field
The invention relates to a lifting seat explosion-proof device of a flexible direct current converter transformer and a using method thereof, belonging to the field of transformer equipment manufacturing.
Background
In a direct-current transmission system, in a net side ascending seat of a flexible-direct transformer, a net side lead and a net side sleeve are connected locally, so that the characteristics of high voltage and high field intensity are achieved, more net side ascending seat explosion accidents caused by discharge between the sleeve and a wire outlet device occur in the use process of the flexible-direct transformer recently, once explosion happens, large-area power failure can be caused, and economic loss and social influence are brought.
When the network side sleeve and the network side lead of the transformer have faults, a large amount of gas is generated suddenly, local stress of the network side lifting seat is overlarge, deformation is overlarge, and internal oil pressure is increased, so that the network side lifting seat is exploded, at the moment, the oil pressure is released as soon as possible, explosion is avoided, or the accident is prevented from further expanding, and the associated loss is reduced.
In order to solve the problems, after the structure of the conventional flexible direct current converter transformer is researched, a lifting seat explosion-proof device of the flexible direct current converter transformer and a using method are provided.
Disclosure of Invention
The invention provides an ascending seat explosion-proof device of a flexible direct current converter transformer and a using method thereof, which can relieve internal high-pressure oil in time when a network side sleeve and a network side lead of the transformer have faults, a large amount of gas is suddenly generated, local stress and deformation of a network side ascending seat are overlarge, so that the internal oil pressure is increased, and the network side ascending seat is exploded, thereby avoiding explosion or preventing further expansion of accidents, reducing the linkage loss, avoiding economic loss and social influence caused by large-area power failure due to the explosion accidents of the network side ascending seat, and effectively solving the problems in the background technology.
The technical scheme of the invention is as follows: a lifting seat explosion-proof device of a flexible direct current converter transformer comprises a net side lifting seat and an explosion-proof system, wherein the explosion-proof system comprises a pressure release device and an oil drain pipe. When the pressure inside the net side lifting seat is increased sharply, the pressure relief device is opened under pressure, and the pressure relief accident is completed to a greater extent.
Further, the pressure release device is a hydraulic overflow valve.
Furthermore, the pressure release device is arranged at the position where the net side lifting seat is easy to deform and break so as to ensure the safety of the net side lifting seat in the pressure release process.
Furthermore, the conduction pressure of the hydraulic overflow valve is higher than that of the overflow valve, so that the overflow valve is firstly conducted under the condition that the pressure is not increased sharply, and the hydraulic oil flows into the oil drainage pool instead of entering the working environment of the transformer.
A use method of a lifting seat explosion-proof device of a flexible direct current converter transformer adopts the explosion-proof device and comprises the following steps: completing the assembly of the net side lifting seat and the pressure release device; the oil drain pipe is fixedly connected with the net side lifting seat through the overflow valve; and adjusting the pressure of the hydraulic overflow valve and the pressure of the overflow valve, so that the opening pressure of the hydraulic overflow valve is greater than the opening pressure of the overflow valve.
The invention has the beneficial effects that: through the improvement to existing equipment, can be in the trouble of transformer net side sleeve pipe and net side lead wire, the proruption a large amount of gas production and net side rise seat local atress too big, the deformation is too big, lead to inside oil pressure to rise, when causing the explosion of net side rise seat, in time carry out the pressure release to inside high pressure oil to avoid the explosion or prevent the accident and further enlarge, reduce the loss of company, avoid because of the net side rises economic loss and the social influence that the seat explosion accident caused the large tracts of land power failure to bring.
