Embodiment 1

[0052] In the box-type substation according to the embodiment of the present invention, the box-type substation includes:

[0053] a box body, the box body includes a first chamber, a second chamber and a third chamber isolated from each other;

[0054] A high-voltage switchgear, the high-voltage switchgear is arranged in the first chamber, and the output high-voltage power is sent to the transformer for step-down (or the boosted high-voltage power output by the transformer is sent to the high-voltage switchgear); as Figure 1-2 As shown, the high-voltage switchgear includes:

[0055] The switchgear and the operation panel 211 are all existing technologies in the art, and will not be described in detail here.

[0056] The closed container 251 is welded as a thick steel plate, the closed container is arranged on the rear side of the operation panel, and the inside is filled with insulating gas, such as sulfur hexafluoride, and the switchgear is arranged in the closed container...

Embodiment 2

[0078] An application example of the box-type substation according to Embodiment 1 of the present invention.

[0079] In this application example, the high-voltage switchgear: 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. The inside of the container is connected; the concentration sensor is an electrochemical sensor, which is set on the closed container, and the output concentration is displayed on the reading meter on the operation panel, which can be the digital display of the display or the display of the scale meter; the operating part It is in the shape of "T", the longer part is used as a wrench, and the shorter part has a matching part, which matches the operation end of the linkage mechanism on the operation panel; so that when the matching part matches the operation end, the wrench can be rotated to realize Operation of switchgear: closing or opening...

Abstract

The invention provides a box type substation. The box type substation comprises a high-voltage switch cabinet, a transformer, a low-voltage switch cabinet, a box body and a grounding apparatus, wherein a first chamber, a second chamber and a third chamber are isolated in the box body; the grounding part comprises a first part, a second part, a third part and a fourth part; the first part comprises a vertical part and a horizontal part, and the vertical part is fixed at the bottom of the second chamber and grounded; the second part comprises a vertical part and a horizontal part, and the horizontal part is partially mounted on the horizontal part of the first part; the third part comprises a vertical part and a horizontal part arranged above the horizontal part of the second part, and the horizontal part is fixed on the horizontal part of the second part and the horizontal part of the first part through a connecting piece; a grounding wire of the transformer is connected with the horizontal part of the third part; and the fourth part comprises a horizontal part and vertical parts on the two sides of the horizontal part, and the vertical parts are fixedly connected with the vertical part of the second part and the vertical part of the third part respectively. The box type substation has the advantages of high safety, small size and the like.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a box-type substation. Background technique [0002] At present, the basic structure of the switch cabinet is: cabinet body, handcart, and the grounding of the handcart is through the fixed cabinet body. The light in the switch cabinet is poor, especially at night. If no additional lighting facilities are provided, the equipment inside cannot be seen clearly, which can easily cause safety accidents. Using the switchgear exposed in the space, the insulation performance of the air is not good, and it is necessary to set a longer distance to meet the insulation requirements, which increases the volume of the switchgear accordingly. Contents of the invention [0003] In order to solve the shortcomings in the above-mentioned prior art solutions, the present invention provides a box-type substation with good grounding performance, good safety performance and small volume. [0004] The purpose of...
