Problems solved by technology
Generally speaking, when the current carrying capacity of the isolating switch is increased, the temperature rise of the conductive copper bar will also be increased. The existing large-capacity isolating switch often cannot solve the problem of the temperature rise of the conductive copper bar well, so that the current Capacity is limited by temperature rise and cannot be further increased

The invention relates to a high-capacity isolating switch which comprises a first isolating switch, a second isolating switch and a connecting terminal, the wire inlet end of the first isolating switch and the wire inlet end of the second isolating switch are connected in parallel through the connecting terminal, and the wire outlet end of the first isolating switch and the wire outlet end of the second isolating switch are also connected in parallel through the connecting terminal. The connecting terminal comprises at least two clamping lug plates which are arranged at intervals, each clamping lug plate is of a flat-plate-shaped structure, and the clamping lug plates are clamped and fixed through the two adjacent clamping lug plates so as to be electrically connected with an external conductive copper bar. While the current capacity of the isolating switch is improved, the temperature rise of the isolating switch is reduced, so that the temperature rise of a product can be prevented from being too high, and the capacity of the isolating switch is further improved.
Description
technical field [0001] The invention relates to the field of switchgear, in particular to a large-capacity isolating switch. Background technique [0002] In today's social environment where the power consumption of life is getting higher and higher, the isolating switch is an important switching device in the power distribution system, and the improvement of its capacity has attracted more and more attention from the industry. Generally speaking, when the current carrying capacity of the isolating switch is increased, the temperature rise of the conductive copper bar will also be increased. The existing large-capacity isolating switch often cannot solve the problem of the temperature rise of the conductive copper bar well, so that the current Capacity is limited by temperature rise and cannot be increased further. Contents of the invention [0003] Therefore, aiming at the above problems, the present invention proposes a structure-optimized large-capacity isolating switc...
