[0036] In the dry-type transformer room of the embodiment of the present invention, the dry-type transformer room includes:

[0037] a casing, the casing includes a top, four sides and a bottom, a door frame and a door are arranged on one of the sides;

[0038] a first group of through holes, the first group of through holes including horizontal and vertical through holes, disposed on the top;

[0039] a second group of through holes, the second group of through holes includes vertical and horizontal through holes, and is arranged on the upper part of the side;

[0040] a third group of through holes, the third group of through holes includes vertical and horizontal through holes;

[0041] grounding devices such as figure 1 As shown, the grounding device is set in the cabinet, including:

[0042] The first part, the first part includes a vertical part 211 and a horizontal part 212, and the vertical part is fixed on the bottom of the cabinet and grounded;

[0043] a second ...

Embodiment 2

[0056] An application example of the dry-type transformer room according to Embodiment 1 of the present invention.

[0057] In this application example, the insulating gas uses sulfur hexafluoride, and its insulation performance is higher than that of air; the sensor uses a pressure sensor and a concentration sensor, and the pressure sensor is arranged on the operation panel and communicated with the inside of the closed container through a pipe; The concentration sensor adopts an electrochemical sensor, which is set on a closed container, and the output concentration is displayed on the reading table on the operation panel. The display can be the digital display of the display or the display of the scale table; the operating part is "T" The longer part is used as a wrench, and the shorter part has a matching part, which matches the operating end of the linkage mechanism on the operation panel; so that when the matching part is matched with the operating end, the wrench can be ...

Abstract

The invention provides a dry-type transformer room, and the room comprises a top part, a side part, a bottom part, a door, and a door frame. Furthermore, the room comprises a first group of through holes which are disposed at the top part; a second group of through holes which are disposed at the upper part of the side part; a third group of through holes which are disposed at the lower part of the side part, wherein the second group of through holes and / or the third group of through holes comprise the through holes in the vertical and horizontal directions. The room is good in heat dissipation performances, is good in safety, and is small in size.

Description

technical field [0001] The invention relates to a dry-type transformer room, in particular to a dry-type transformer room. Background technique [0002] At present, the basic structure of the dry-type transformer room is: cabinet, handcart, and the grounding of the handcart is through the fixed cabinet. When the handcart enters and pulls out of the cabinet, the grounding device of the cart and the grounding of the handcart Device mating, disengagement. When the handcart exits, the high-voltage equipment in the dry-type transformer room is exposed, and the operator is easy to touch it by mistake, which may cause personal injury. Contents of the invention [0003] In order to solve the shortcomings in the above-mentioned prior art solutions, the present invention provides a dry-type transformer room with good safety performance and good grounding performance. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A dr...
