Zhejiang Dahu Electric Co., LTD is a professional manufacturer of high and low voltage transformers.
Detailed information about LZZW-10Q 10KV high voltage current transformer (CT) is listed below:
Product Overview:
LZZW-10Q current transformer is a kind of outdoor epoxy resin casting fully enclosed structure of high-voltage current transformer, suitable for rated frequency of 50Hz, rated voltage of 10KV and the following electric power system, for current, electric energy measurement and relay protection.
Technical Parameters:
Rated insulation level: 12/42/75KV, which ensures the safe operation of the transformer in high-voltage environment.
Load power factor: cosφ= 0.8 (lagging).
Rated secondary current: 5A or 1A, to meet different measurement and protection needs.
Product implementation standard: GB1208-1997 Current Transformer.
Instrument security factor: Fs≤10.
Surface creepage ratio distance: to meet the requirements of level of filth.
Ambient temperature: -25ºC-40ºC, the average daily temperature does not exceed 30ºC.
According to the user's requirements, can also make the complex ratio type.
Product features:
Arc resistance, aging resistance, UV resistance: long service life.
Busbar-type plastic shell insulation: there is a mounting plate in the lower part of the product for fixed installation, and a window hole in the center for the primary busbar to pass through.
Small size and easy to install: easy to install and maintain.
Precautions:
The transformers are used in AC circuits with rated voltage not exceeding 0.66kV and long-term operating current not exceeding 1.2 times the rated value.
The products are of reduced polarity, primary wiring symbols P1, P2, the corresponding secondary wiring symbols S1, S2.
Measuring instruments connected to the S1, S2 terminals, the total impedance of the connected instruments (including wiring) should not exceed the rated load of the transformer.
The secondary open circuit of the transformer is strictly prohibited in operation.
The above information provides a detailed description and key technical parameters of LZZW-10Q 10KV high voltage current transformer, which we hope will be helpful to you.
