Embodiment 1

[0049] The novel railway box change of the embodiment of the present invention, the novel railway box change comprises:

[0050] The box body includes a first chamber, a second chamber and a third chamber which are isolated from each other; the top of the second chamber is a double-layer structure, and is provided with a cooling fan for outward heat dissipation; the bottom is provided with an inspection port, It is convenient for the staff to enter the underground maintenance through the inspection port, and the cover plate is set on the inspection port and opened when necessary;

[0051] 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:

[0052] The switchgear and the operation panel 211 are all exist...

Embodiment 2

[0075] An application example of the novel railway box-type transformer according to Embodiment 1 of the present invention.

[0076] 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: clo...

Abstract

The invention provides a novel railway box-type substation, which comprises a high-voltage switch cabinet, a transformer, a low-voltage switch cabinet, a box body, a lighting device, a switch and a lighting lamp, wherein the box body comprises a first chamber, a second chamber and a third chamber which are isolated from one another; the top of the box body is of a dual-layer structure; an access port is arranged in the bottom of the box body; a cover plate is arranged on the access port; the lighting device is arranged in the first chamber or the second chamber or the third chamber and comprises a support part; the support part is arranged at the inner side of a door frame; the switch is arranged on the support part and is provided with an operating part which is pushed by a chamber door to turn off the switch when the chamber door is closed and turns off the switch when the chamber door is opened; the lighting lamp is fixed on the inner wall; and the switch controls the lighting lamp to be turned on or off. The novel railway box-type substation has the advantages of good safety performance, small volume and the like.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a novel railway box transformer. 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 gas-isolated switchgear with good safety performance, small size and good grounding performance. [0004] Th...
