Application

 

 


Features & Advantages


Core


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity. 45° mitring and 5-steps overlapping structure is adopted for the core design, thus to greatly reduce no-load loss and no-load current.

 

To precisely calculate resonance frequency and intensity and avoid cavity resonance generated by the core structure during operation, simulation analysis is carried out for core mould design. Flexible connections are made between core and coils, core and bogie. With these measures adopted, the noise level is reduced by 10~15dB compared with the international standard.

HV winding


HV winding is manufactured with high quality copper wire, reinforced with glass fiber and being casted with epoxy resin at vacuum state with pressure, having the resin fully impregnated into the coils in the most professional imported equipment. Therefore, product's partial discharge is especially low, for example, transformer of 10kV-level has a partial discharge less than 5 pC.

 

During the HV winding design, rational structure is adopted to improve the electric distribution. With the lighting impulse wave simulation calculation and analysis being carried out with special auxiliary software, product's anti-lightning impulse capacity is greatly improved.

LV winding


LVwinding (with the rated power equal to or higher than 400kVA) is manufactured with high quality foil conductor, resulting in excellent ampere-turn balance, low transverse magnetic flux leakage and higher anti-short circuit capability. By designing reasonable air conduit in the windings to increase the heat-dispersion surface, transformer's temperature rise is effectively controlled and the overload capacity is greatly improved.

Inspection and Acceptance


On receiving the series reactor, please check immediately the product type and other
specifications with reference to the rated plate on the series reactor, to determine whether they
conform to the requirements written in the contract. Meanwhile, please check the technical
documents and attachments by referring to the shipping list. For series reactor itself, please check
the following items:
1) Whether there is oil-leakage from the series reactor tank.
2) Whether the series reactor or its attachment are damaged.
3) Whether the wearing parts are damaged, for example, the pressure relief valve, signal
thermometer, bushing, gas relay and multi-function tube-type oil-level indicator.
Note:
Generally, product rated 800kVA or below 800kVA is not equipped with signal thermometer
and pressure relief valve. Product rated 800kVA or below 800kVA is not equipped with gas relay.
