Abstract
The utility model discloses an anti-inflowing and anti-explosion oiled paper capacitance type transformer sleeve which comprises a wiring terminal, an oil conservator, an upper insulator, an installing flange, a flange cylinder, a lower insulator, a pressure-equalizing ball and a capacitance core used as a main insulator, wherein a strong spring for sealing is arranged in the oil conservator, an inflation valve for enabling the inside of the sleeve to be in micro-positive pressure is arranged on the oil conservator, and a pressure meter communicated with the inside of the sleeve is arranged on the installing flange. According to the anti-inflowing and anti-explosion oiled paper capacitance type transformer sleeve, the pressure meter is arranged on the installing flange, thus the pressure inside the sleeve can be monitored. Due to the micro-positive pressure inside the sleeve, the sleeve can be effectively prevented from inflowing, thus safety accidents caused by inflowing of the sleeve are avoided.
Description
Technical field
The utility model relates to a kind of bushing shell for transformer, is specifically related to a kind of anti-water inlet blast protection oil-impregnated paper condenser type transformer bushing.
Background technology
Bushing shell for transformer service conditions is very harsh, is subject to many-sided combined influences such as voltage, electric current, pulling force, vibrations, wind-force, atmosphere filth during operation, once produce fault, very easily causes fault spread, and loss is serious.Therefore, sleeve pipe is also the accessory of paying close attention to the most in each main frame accessory.
Bushing shell for transformer is blasted, and may cause heavy economic losses and the personnel of threat life security, and the main cause of its generation has:
1, inside pipe casing water inlet is still the main cause that incipient failure occurs, and mostly is catastrophic discontinuityfailure, and harmfulness is very big.Main cause is (when the reason of destruction sealing may exist defect or sleeve pipe to install for structural design, the misoperation of installation personnel causes) under non-sealing condition, and inside pipe casing infiltrates moisture content.
2, inside pipe casing disruptive discharge, causes insulating oil to decompose in a large number generation gas, causes inside pipe casing pressure excessive, thus the accident of blasting.
Summary of the invention
In order to overcome the shortcoming of existing oil-impregnated paper condenser type transformer bushing, the purpose of this utility model is to provide a kind of anti-water inlet blast protection oil-impregnated paper condenser type transformer bushing, and this sleeve pipe reliability is high, can guarantee security of operation, easily realize.
The purpose of this utility model is achieved through the following technical solutions:
A water inlet blast protection oil-impregnated paper condenser type transformer bushing, comprises binding post, conservator, upper insulation, mounting flange, flange cylinder, lower insulation, voltage equalizing ball and as the capacitor core of main insulation, is provided with sealing brute spring in conservator; It is characterized in that: the charging valve that makes inside pipe casing keep pressure-fired is installed on conservator; The Pressure gauge being communicated with inside pipe casing is installed on mounting flange.
The utility model can be provided with the pressure sensor that can automatically monitor inside pipe casing pressure on mounting flange.In order to monitoring sleeve internal pressure size.On mounting flange, be provided with oil sealed sampling device, this oil sealed sampling device is directly connected with the needle tubing that draws oil sample.
In the utility model, capacitor core, as main insulation, makes sleeve pipe integral sealing by seal between brute spring and parts.Installing hole is left in sleeve pipe conservator upper end, and installing hole is communicated with inside pipe casing and outside, and in sleeve pipe production process, this installing hole stays the fabrication hole vacuumizing with immersion oil, before sleeve pipe dispatches from the factory, charging valve is installed on installing hole, inside fills pressure-fired.
On sleeve pipe mounting flange, leave installing hole, installing hole is communicated with inside pipe casing and outside, and in sleeve pipe production process, this installing hole seals with plug cock, before sleeve pipe dispatches from the factory on installing hole setting pressure table,
The utility model is provided with charging valve on conservator, both inflatable, again can repairing; In sleeve pipe, fill pressure-fired, setting pressure table on mounting flange, can monitoring sleeve internal pressure size.Due to inside pipe casing pressure-fired, can effectively prevent from overlapping water inlet tube, thus the security incident of avoiding sleeve pipe to cause because of water inlet.On mounting flange, have Pressure gauge, can monitoring sleeve integral body good seal whether, again can monitoring sleeve internal pressure, prevent the sleeve pipe accident of blasting because internal pressure is excessive.If load onto pressure sensor, can realize intelligent control.Sleeve pipe has built-in electrical insulation fault can cause pressure to raise, the system even automatic cut-off power of can reporting to the police.On mounting flange, also have oil sealed sampling device, under slight positive pressure state, can directly with getting spindle pipe, be connected, without venting, very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local enlarged diagram of A portion in Fig. 1;
Fig. 3 is the local enlarged diagram of B portion in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of anti-water inlet blast protection oil-impregnated paper condenser type transformer bushing, see Fig. 1, this sleeve pipe comprises binding post 1, conservator 2, upper insulation 3, mounting flange 4, flange cylinder 5, lower insulation 6, voltage equalizing ball 7 and capacitor core 8, capacitor core 8, as main insulation, makes sleeve pipe integral sealing by seal between brute spring 9 and parts.Charging valve 10 is installed on conservator 2, and is filled pressure-fired at inside pipe casing.Pressure gauge 11 is installed on mounting flange 4, and Pressure gauge 11 and inside pipe casing are communicated with, can monitoring sleeve internal pressure size.If the pressure sensor that can automatically monitor inside pipe casing pressure is installed on mounting flange, in order to monitoring sleeve internal pressure size, can realize intelligent control, sleeve pipe has built-in electrical insulation fault can cause pressure to raise, the system even automatic cut-off power of can reporting to the police.On sleeve pipe mounting flange 4, get oily device 12, can directly with the needle tubing that draws oil sample, be connected.
