GibraltariansDifference between box transformer and transformerReversal of supply and demand

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.

The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.

Gibraltarians.Power saving analysis of transformer

The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring,GibraltariansInspection items of dry-type transformer, and D (or D) is triangular wiring.

.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

When the transformer is out of phase, if the second phase is blocked,Gibraltarians480v dry type transformer, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:

Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.

It is understood that in China, transformers have experienced the whole process of replacing many series products such as sss11. As early as the middle and late 1980s, S7 Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb1300-73 and jb500 - Specifications operating in the power network at that time. Since the 19th century, urban power grids have been transformed all over the country, and S9 series distribution transformers have been used to replace S7 Series. In recent years, S13 and S15 commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is 50% - 80% less than that of S9 transformer.

Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible,GibraltariansPower transformer 50, the dry-type transformer room can also be soundproofed and decorated, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

After sampling the pose period of overcurrent protection shall be set to zero, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.

How much is the power transformer

install.When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.

The insulation of the through core anchor bolt clamping the iron core is damaged, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, 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.

Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.

When the screw of the through core extruder holding the iron core of the transformer is loose there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.
