HPA and anBox type transformerProduct production and function

Careless maintenance and insulation damage

Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.

HPA and an.The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.

After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.

.Connection group structure of dry-type transformer

When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate),HPA and anS13-50 power transformer, or it can be replaced by changing the oil.

Seal oil leakage

When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.

How to maintain dry-type transformer?

When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.

Total quality management.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 vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer,HPA and anDifference between transformer and box transformer,HPA and an4000kva power transformer, and the vibration reduction solution is made at the cable bridge.

The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.

Power transformer

install.For 630kVA power engineering transformer plastic parts are selected in the middle of iron core, and long-term scalding of iron core will lead to insulation aging.
