Azet volcanic (5) the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.
(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.
Antigua and Barbuda .The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;
Oil leakage of cast iron parts
.For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.
Oil immersed transformer company
Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube,Antigua and Barbuda 25kV power transformer, carry out it twice, and then draw the oil sample.
The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts,Antigua and Barbuda Test items of power transformer, with good strength and stiffness which is conducive to adjusting the data and has a unique and neat style.
The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by 100kW motor, so the usual load is 200 KW, CST = 0. One 750kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only 34%

packing.Power transformer plant
The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

How to reduce the failure of dry-type transformer?
Test results.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.
Transformer
The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.
Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).
