Description

A fully sealed series reactor

technical field

The utility model relates to a reactor in the electric power industry, in particular to a fully sealed series reactor.

Background technique

With the rapid development of my country's economy, the demand for electricity is increasing day by day. However, the traditional series reactor has poor heat dissipation, high temperature, low dielectric strength, and poor operational reliability; poor integrity, low mechanical strength, and poor dynamic and thermal stability; large volume, inconvenient transportation, and cumbersome installation and maintenance.

Utility model content

In order to solve the above problems, the utility model provides a fully sealed series reactor with good heat dissipation, low temperature rise, high insulation strength and maintenance-free.

The purpose of this utility model is achieved by the following scheme: a fully sealed series reactor, including a coil, an iron core and a sealed box, the coil and the iron core are arranged in the sealed box, and the coil is sealed with a non-weft The belt is fastened and dipped in insulating varnish. The upper and lower ends of the iron core are respectively provided with iron yokes. The iron yokes are fastened and connected through the bridge plate. Rubber mat.

In the above solution, the iron core is made of silicon steel sheet.

In the above solution, the tension bolt is made of non-magnetic material.

In the above solution, the coil is wrapped and fastened with a weft-free tape, and dipped in insulating varnish.

In the above solution, oil tanks are arranged on both sides of the sealed box, and the inner wall of the oil tank is a corrugated structure.

Compared with the prior art, a fully sealed series reactor of the utility model has the following beneficial effects:

1. Since the coil is wrapped and fastened with latitude-free tape and dipped in insulating varnish, the insulation performance is improved.

2. The iron core is made of high-quality low-loss cold-rolled oriented silicon steel sheet, which has been impregnated. The installation part is equipped with rubber shock-absorbing measures to reduce the noise when the product is running.

3. The sealed box is a fully sealed structure, and the internal insulating oil is not connected to the atmosphere, which reduces leakage and avoids daily maintenance.

4. The inner wall of the oil tank is of corrugated structure, which enables the product to operate under different ambient temperatures, and the interior is always filled with insulating oil, and makes the internal pressure consistent with the external pressure, so that excessive pressure will not be generated due to excessive temperature; it has anti-explosion, anti- Fire function.
