Abstract

The utility model discloses a seal leakage test device for an oil-immersed transformer. The device comprises a box. The box is equipped with a pressure gauge and a G1 bolt. The box is connected with a compressed-air source through a compressed-air transmission connector, and a flow control valve is mounted on the compressed-air transmission connector. According to the utility model, the seal leakage test device is not limited by the conventional seal operation, and effectively reflects the sealing state by intuitive data, thereby solving the problems of complication of manual operation and low production efficiency.

Description

A kind of device of oil-filled transformer sealing leak test
Technical field
The utility model relates to a kind of device of oil-filled transformer sealing leak test, for detection of the sealing condition of oil immersion-type distribution transformer.
Background technology
Traditional oil-immersed type transformer fuel tank sealing leak test, is filled with in casing with nitrogen, and whether quiet putting 12 hours, leak gas with suds inspection sealing place.Therefore, there is following shortcoming:
1. need the equipment of making nitrogen or outsourcing nitrogen, when increasing production cost, also will note the security of nitrogen pot.
2. can not hold the fill gas scale of construction in casing, if be filled with too much, internal pressure increases, and can cause casing permanent strain.
3. need to make the connector of gas-filled tube and fuel tank, and change frequent.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of device of oil-filled transformer sealing leak test, financial resources, manpower and time-consuming while sealing leak test to solve oil-filled transformer, and guarantee the indeformable problem of product box body profile.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A device for oil-filled transformer sealing leak test, comprises casing, and described casing is fitted with tensimeter and G1 bolt, and casing is connected with compressed air source by compressed air delivery joint, on this compressed air delivery joint, flowrate control valve is installed.
Described flowrate control valve is copper ball valve.
According to above technical scheme, with respect to prior art, the utlity model has following advantage:
1. because the leak test gas adopting is pressurized air, directly effectively utilize the compressed air piping of on-site, save cost;
2. package unit is integrated part, is installed on several casings simultaneously, waits for the processing of continuous sealing leak test, and production efficiency significantly improves;
3. without calculating inflationtime, only pneumatic hose need be inserted in rapid-acting coupling fast, open valve, directly check gauge hand, can understand the pressure condition in casing;
4. quiet putting after 12 hours, checks gauge hand numerical value, can understand which box sealing defective (gas leakage);
This sealing leakage testing device has been broken away from the limitation of traditional seal operation, effectively utilizes the situation of numerical response sealing intuitively, has solved the slow difficult problem of manually-operated triviality and production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: rain glass 1; Pressure tapping 2; Valve joint 3; Casing 4; G1 bolt 5; Copper ball valve 6; Compressed air delivery joint 7.
Embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation; Below with reference to accompanying drawing, explain the technical solution of the utility model.
As shown in Figure 1, the device of oil-filled transformer sealing leak test described in the utility model, comprises casing, and described casing is fitted with tensimeter and G1 bolt, and casing is connected with compressed air source by compressed air delivery joint, on this compressed air delivery joint, flowrate control valve is installed.Wherein: described flowrate control valve is copper ball valve, and copper ball valve is connected with casing by ball valve joint; Compressed air delivery joint is rapid-acting coupling.
Using method of the present utility model is as follows:
Soldering is carried out in the lower end of G1 bolt one end and casing, and tensimeter is by pressure tapping and the soldering of casing upper end, and tensimeter carries out screw threads for fastening by O-ring seal and pressure tapping, and copper ball valve, rapid-acting coupling and ball valve joint pass through screw threads for fastening; Whole device forms one.
When sealing leak test, by the G1 disassembling bolts on casing, then the G1 bolt on device is installed on casing, with pneumatic hose, entangle rapid-acting coupling, move copper ball valve, can in casing, be filled with pressurized air; When the manometric pointer of observation meets the requirements of pressure value, valve-off, pulls out tracheae, continues the leakage test of other casing.

Claims (2)

1. the device of oil-filled transformer sealing leak test, it is characterized in that: comprise casing, described casing is fitted with tensimeter and G1 bolt, and casing is connected with compressed air source by compressed air delivery joint, on this compressed air delivery joint, flowrate control valve is installed.
2. the device of oil-filled transformer sealing leak test according to claim 1, is characterized in that: described flowrate control valve is copper ball valve.
