Problems solved by technology

[0004] 1 Sound insulation and sound absorption are independent structures, resulting in complex overall structure, difficult installation, and restricted construction progress;
[0005] 2 Sound insulation rock wool color steel sandwich panel, the strength of the panel will be reduced after cutting on site, and it will be easily damaged during hoisting;
[0006] 3. When the transformer is replaced and overhauled, the reuse rate of the removed sound-insulating rock wool and color steel sandwich panels is low, and bas

Embodiment Construction

[0012] A "BOX-IN" technical improvement and perfection

[0013] 1 "BOX-IN" front panel and top panel adopt sound insulation and sound absorption composite structure, which makes the structure simple and easy to install;

[0014] 2 The sound insulation and sound absorption board adopts self-supporting structure, and the internal design has a skeleton, which can enhance the strength of the board;

[0015] 3 All sound insulation and sound-absorbing panels are shaped and manufactured, without on-site cutting and processing, and the reuse rate is high;

[0016] 4 Under the condition of not affecting the movement of the transformer, the "BOX-IN" structure has been optimized, and part of the sound insulation, sound-absorbing panels and steel frames do not need to be disassembled, which reduces the workload during maintenance;

[0017] 5 The "BOX-IN" node is designed as a bolt connection, which can be disassembled quickly without loosening or falling off, avoiding potential safety ha...

Abstract

The invention relates to a new technology for the noise treatment of a large-sized converter transformer by using a firewall and a valve wall at two sides of the converter transformer to carry out closed acoustic treatment to a main body of the transformer. The main body of the transformer is placed in a 'BOX'. In order to provide convenience for examining and repairing equipment, a self supporting sound insulation and absorption compound structure is adopted in both a 'BOX-IN' front board and a 'BOX-IN' top board. As partial sound insulation and absorption boards and steel frames can not be disassembled, all nodes are connected by bolts, thus being assembled and disassembled rapidly. All parts are manufactured by molding, do not require cutting on site and have high processing and reusing rate.

Description

technical field [0001] The invention relates to a method for controlling the noise of a domestic large-scale converter station, in particular to a technology for controlling the noise of a large-scale converter transformer. Background technique [0002] At present, there are mainly two effective noise reduction measures for converter transformer noise in domestic large-scale converter station noise control projects. One is to install a large-scale ventilation and noise reduction device in front of the converter transformer (Beijing Lvchuang patented technology) The other is "BOX-IN" noise reduction technology. [0003] The so-called BOX-IN is to use the firewall on both sides of the converter transformer and the valve hall wall to carry out closed sound insulation treatment on the transformer body, and put the transformer in the "BOX", which is similar to the noise reduction method of installing a sound insulation room and a sound insulation cover. "BOX-IN" was applied for ...
