HY-R20 automatic wear bushing machine is very powerful: automatic feeding tube, automatically cut off, automatic wear sleeves, with CNC easy to use, quick, quality assurance, greatly improving production efficiency, then the automatic assembly machine wear bushing should pay particular attention to the following points:

Temperature conditions: the assembly must be clean, dry conditions in addition to outside, can be assembled preferably at a temperature of 40-50 ℃. Because condenser core temperature above the ambient temperature at 10-15 ℃ temperature can reduce the impact of moisture, so preferably before assembling the casing parts and condenser core is heated to 70-80 ℃, keep 3-4h, so exclusion of surface moisture, the assembly has not yet finished when the temperature is reduced as much as possible.

Seal the top of the casing: the casing at the top of the casing seal itself can be divided into cable lead seals and seal wear. Now most of the oil Roof main transformer substation equipped elastic corrugated board, which together with the compression spring to regulate the temperature change. When assembling the elastic corrugated board, positive and negative compression nut ring seal between the gasket and the conservator's sure to fit properly on the catheter to prevent crack corrugated board, in order to achieve sealing effect. Casing wear lead cable structure, if the top of the patch panel, between the conductive Mifengbuyan dense head, the rain will be along the top of the casing patch panels, electrical conductivity along the head and cable ducts penetrate inside the transformer. Moisture into the transformer leads the roots, will lead to damp breakdown, resulting in power outages. To avoid this situation, the bolt must be pressed, to ensure sealing.

The small central flange sleeve: the outermost shield plate capacitive screen that is grounded electrical panel, with a soft single strand 1.5mm2, and put a small plastic tube lead to the grounding rod conductive sleeve, this sleeve called measurement terminals, pay attention to the small casing sealing and insulation of the cord leads to the assembly. Maintenance, casing level should lie down, at the end of the small screen casing upward, breaking the small end of the sleeve to check the wire screen, etc., can also make the appropriate repairs. When casing pressure test run and make its external ground cover should be well grounded.

Pressure the ball should be adjusted appropriately: Pressure the ball in the center of the tail pipe, conduit along the axial twist up and down in order to fit with the main wire assembly. Pressure the ball must be tight, otherwise it will all happen between the discharge pressure of the ball and the casing. Pressure the ball in addition to blocking the bottom, nuts, oil drain plug and other metal parts, but also to meet the electrical strength requirement that equalizing the ball position adjustment, rear casing can be reduced to the tank wall and winding insulation creepage distance distance, improve convergence and axial potential distribution. Such as improper adjustment, flash slide will produce spherical discharge, resulting in dielectric breakdown, the electrical properties of the casing great harm; oil sample valve, drain plug quality is better, should not have rust; pads should be of good quality; vacuum When oiling, should first establish a vacuum, check the various parts of the casing seal case, then keep the residual pressure in 133.3Pa below the stipulated time oiling. After breaking the vacuum oiling, casing oil level decreased slightly, if the need for timely fuel starvation phenomenon. Taking into account the oil sample, should be slightly more note some oil.

Automatic assembly machine wear bushing sleeve experimenting in particular should pay attention to its placement position measurement of dielectric loss, because the casing of small capacitance, when the position is not the same, because the high voltage electrode and measuring electrode architecture for not fully grounded object impact walls and floors stray impedance measurement results will have a significant impact casing. Different positions, these effects not identical, so are often great dispersion measurements. Therefore, when measuring the dielectric loss and other tests, should be placed in a perpendicular sleeve casing properly grounded planes carried out, not to be placed horizontally or with insulated cable sleeves hung up at any angle measurements to ensure measurement data accurate.
