A Dry Reactor Air Duct Air Sweeping Equipment

Abstract

The invention discloses an air sweeping device for a dry-type reactor air duct, which includes an air blowing device and an air delivery pipe. The air delivery pipe includes several sections of universal bamboo tubes connected in sequence; Compressor, flexible pipe, air gun, the universal bamboo tube at the end of the air pipe is ventilated and connected with the air outlet of the air gun. The gas transmission pipe formed by connecting several sections of universal bamboo tubes in sequence in the present invention can meet the requirements of airtightness and support, and will not shake abnormally under the effective air outlet pressure; the universal bamboo tube can be moderately bent. , send the air pipe into the air duct of the reactor, send the compressed air to the air duct of the reactor through the air duct, and realize a certain degree of direction adjustment in the air duct, and carry out precise air sweeping of impurities and dust at the corners of the air duct .

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to air sweeping equipment for a dry-type reactor air duct. Background technique [0002] As my country's economic development is getting faster and faster, the demand for electricity is also increasing, so the country is also focusing on strengthening the construction of DC projects. An important piece of equipment in the DC converter station is the reactor, which is usually connected in series / parallel between the converter and the DC line, or installed in the filter group, and is one of the important equipment in the UHV converter station. There are two types of reactors: dry type and oil-immersed type, each with its own advantages and disadvantages. Dry type reactors are mostly used in the AC / DC filter group and blocking reactors in the station. When a disturbance or accident occurs in the DC system, the reactor can suppress the mutation speed of the DC current to a...

Problems solved by technology

At the entrance of the upper air duct 1001, bird pests or insect pests such as bird nesting are prone to occur, which will affect the distribution of the electric field and damage the body, and the blockage of the air duct will cause abnormal heat dissipation inside the reactor, resulting in local overheating and affecting the safe and stable operation of the power grid. Therefore, the air duct needs to be cleaned every time it is overhauled.

However, the air duct of the dry-type reactor is narrow and long, with a width ranging from 20 to 50 mm and a length of 5 to 10 m. It is difficult to clean. The commonly used air blowing method can only roughly clean the air duct.

The prior art provides a dry-type reactor cleaning device, which uses a retractable rod made of refined stainless steel with a hardened steel riser to go deep into the air duct for cleaning, but it is used in dry reactors in DC power stations. The cleaning device can only be inserted into the air duct from the bottom of the reactor to clean from bottom to top. Due to the influence of gravity, foreign objects may fall back or reattach to other heights of the air duct, and the cleaning effect is not good.
