Problems solved by technology
[0004] The currently used power switch and its matching switchgear are relatively large in size, and a large amount of SF6 gas is used, which can bring serious pollution to the environment. As far as the power switch itself is concerned, it has poor scalability and is inconvenient to install. Due to the limitation of the installation site, the actual installation or replacement of power switches and switch cabinets has certain difficulties
Also, due to factors such as insulation performance, material material, and use environment, the reliability of power switches and switchgears is poor, which greatly increases manufacturing costs and operation and maintenance costs.

Embodiment Construction
[0014] 24kV small vacuum load switch (circuit breaker) cabinet, including cabinet body 1, three load switch (circuit breaker) vacuum interrupters 2, three load switch (circuit breaker) opening and closing conductive components, and three vacuum interrupters Combination and separation operating mechanism and three solid-sealed poles 3 . A metal partition 4 is horizontally fixed in the cabinet body 1, and the metal partition board 4 divides the inner space of the cabinet body 1 into an upper space and a lower space. The upper space is the main busbar room 5 . The upper part of the lower space is the switching element transmission chamber 6, the lower part of the lower space is the cable chamber 23, and the front space of the main bus chamber 5 and the switching element transmission chamber 6 is provided with a transmission mechanism operating chamber 25 and a secondary element installation chamber 24 in sequence. See figure 2 . The cable room 23 can be equipped with groundin...

The invention discloses a 24kV small-sized vacuum load switch (circuit breaker) cabinet which comprises a cabinet body and three vacuum interrupters (load switches or circuit breakers). The 24kV small-sized vacuum load switch cabinet is characterized in that a metal partitioned board is transversely fixed in the cabinet body; the three vacuum interrupters are respectively poured in three embedded poles; and the three embedded poles are fixed at three embedded pole through holes which are linearly arranged on the metal partitioned board and are integrated with the cabinet body. The 24kV small-sized vacuum load switch cabinet breaks through a traditional structural form that the load switch cabinet is produced and then is filled with the vacuum load switch and has the advantages of small size, raw material saving, large on-off capability, safety, reliability, long electric life, capability of frequently operating, low maintenance frequency and the like. The 24kV small-sized vacuum load switch cabinet has a remarkable separating fracture, can be equipped with an earthing switch with a closing function and an electric spring mechanism and can be used for remotely controlling.
Description
technical field [0001] The invention relates to a switchgear, in particular to a switchgear with a small vacuum load switch (circuit breaker) as an independent upper unit. Background technique [0002] The power switch is one of the key equipment in the power supply industry. It is used to protect the safe operation of power stations and generator sets. It is used as a switch for power transmission and transformation lines. It is one of the key components in relay protection and plays a role in safe power transmission. Function, mines, oil fields, and enterprises are used as equipment for industrial power distribution and electric traction. From this point of view, power switches play an important role in distributing electric energy and protecting power distribution equipment. [0003] At present, my country's medium-voltage distribution network is basically based on 10kV, but with the rapid economic development, especially in economically developed areas, the existing 10kV...
