Problems solved by technology
[0002] At present, most switchgears in the domestic market have certain disadvantages. Some switchgears have pressure release channels that can only meet the internal fault energy release requirements of one circuit; some double-layer switchgears use two sets of independent functional compartments, that is, two The main busbar room, instrument room, handcart room, and cable room have the disadvantages that either the size of the cabinet is too large, or the pressure release channel is too small or even has no channel when the internal fault occurs, and the faulty air flow inside the cabinet cannot be discharged out of the cabinet in time. , creating a safety hazard

Embodiment Construction
[0011] The present invention is specifically described below in conjunction with the accompanying drawings:
[0012] Such as figure 1 As shown: the present invention includes an instrument room A, an upper handcart room B, a lower handcart room C, a cable room D, a main bus room E, and a lower handcart room pressure release channel F arranged in the cabinet body 1, front and rear of the cabinet body There is a cabinet door 2 at the end, an instrument room A is provided at the front upper end of the cabinet body 1, and the upper middle part of the cabinet body is the upper handcart room B (the upper handcart room is located at the corresponding position of the existing middle-mounted switchgear handcart room), Behind the instrument room, there is a pressure release channel 3 for the upper handcart room. Behind the upper handcart room, there are main busbar room E and cable room D. The handcart room includes the upper handcart room and the lower handcart room. The lower handcart...

A double layer switch installation with multi-pressure release passages comprises a cart chamber in a cabinet body, a meter cabinet, a cable chamber and a main bus-bar chamber. A meter cabinet is arranged on the front and upper end of the cabinet. An upper cart chamber is arranged at the front and middle portion of the cabinet body. A pressure release passage of the upper layer cart chamber is arranged at the back of the meter cabinet. A main bus-bar chamber and a cable chamber are arranged at the back of the upper layer cart chamber. The invention has the advantages that the double layer switch installation has two independent power supply loops without changing the contour dimension of the switch installation cabinet body and the neighbouring switch installation can operate safely when the inner arcing fails in each compartment so that the switch installation operates more reliably.
Description
technical field [0001] The invention relates to a double-layer switchgear with multiple pressure relief channels. Background technique [0002] At present, most switchgears in the domestic market have certain disadvantages. Some switchgears have pressure release channels that can only meet the internal fault energy release requirements of one circuit; some double-layer switchgears use two sets of independent functional compartments, that is, two The main busbar room, instrument room, handcart room, and cable room have the disadvantages that either the size of the cabinet is too large, or the pressure release channel is too small or even has no channel when the internal fault occurs, and the faulty air flow inside the cabinet cannot be discharged out of the cabinet in time. , forming a security risk. Contents of the invention [0003] The purpose of the present invention is to provide a small footprint, safe and reliable double-layer switchgear with multiple pressure relea...
