Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0028] Such as Figure 1-4As shown, the present invention provides a fire-proof and explosion-proof structure for the plugging of the converter transformer valve side bushing in the converter station, which has a simple structure, scientific and reasonable design, and is easy to use. Well, the sealing performance is ideal. The present invention includes a fireproof and explosion-proof plate 1 sealed and installed on the fireproof wall 15 of the valve hall of the power station. The center of the fireproof and explosion-proof plate 1 is provided with a converter bushing installation hole 2 that matches the converter bushing 14. The installation holes 2 of the converter bushing are distributed obliquely, and the inclination thereof is consistent with the gradient of...

Abstract

The invention discloses a fire-proof and explosion-proof structure for valve-side bushing plugging of a converter transformer in a converter station, which solves the problems of unsatisfactory fire-proof and explosion-proof performance, electromagnetic isolation effect, and sealing performance at the installation place of the converter transformer bushing in the prior art. The invention includes a fire-proof and explosion-proof plate and a rheometer bushing installation hole. The gap is filled with aluminum silicate needle-punched blanket; the fireproof and explosion-proof board includes the first metal surface structure rock wool composite board, the second metal surface structure rock wool composite board and non-magnetic stainless steel impact-resistant board, aluminum silicate needle-punched blanket layer It is located between the hole wall of the rheological bushing installation hole part of the first metal surface structure rock wool composite plate and the second metal surface structure rock wool composite plate and the outer wall of the rheological bushing. The invention has scientific and reasonable design, convenient use, good fireproof and explosion-proof performance at the installation place of the rheological bushing, good electromagnetic isolation effect and ideal sealing performance.

Description

technical field [0001] The invention relates to a fire-proof and explosion-proof structure for plugging bushings on the valve side of a converter transformer in a converter station. Background technique [0002] The valve hall of the power station is a closed building for placing converter valves, which requires excellent electromagnetic shielding performance. Shield the electromagnetic interference generated by the commutation. The walls and floors are all paved with non-magnetic stainless steel plates. The design of the rheological bushing needs to be installed through the wall. Explosion-proof structure to meet the fire and explosion-proof requirements. The existing fire-proof and explosion-proof structure of the rheological bushing installed in the valve hall of the power station has unsatisfactory fire and explosion-proof performance and electromagnetic isolation effect, and the sealing performance of the installation gap of the rheological bushing is also poor. not id...
