Embodiment Construction

[0013] Attached below Figure 1-2 Embodiments of the present invention are described.

[0014] 24KV vacuum high voltage circuit breaker with small modular spring operating mechanism, such as figure 1 and 2 As shown, there is a box body 4, and the inside of the box body 4 is provided with a solid-sealed pole 2 and a VSH small modular spring operating mechanism 1, and the interior of the solid-sealed pole 2 is provided with a vacuum interrupter 3. The vacuum interrupter 3 is cast on the solid-sealed pole 2 with APG epoxy resin, which simplifies the complex assembly and adjustment links of the three-phase main circuit, reduces the possible damage to the vacuum interrupter during the assembly process and reduces the number of bolts used. The connection is loosened due to vibration. The unique epoxy resin pole has anti-aging, high temperature resistance, low temperature resistance and high mechanical strength, which completely avoids the external surface of the vacuum circuit bre...

Abstract

Provided is a 24KV vacuum high-voltage circuit breaker equipped with a small modular spring operating mechanism. The circuit breaker includes a box body. A solid-sealed polar pole and a VSH small modular spring operating mechanism are arranged inside the box body. A vacuum interrupter is arranged inside the solid-sealed polar pole. An insulated pull rod is arranged at the bottom of the vacuum interrupter. A transmission shaft in the VSH small modular spring operating mechanism is connected with the insulated pull rod through a connecting rod and crank arm structure so the VSH small modular spring operating mechanism can drive the insulated pull rod and the vacuum interrupter to realize closing and opening. The VSH small modular spring operating mechanism is applied to the 24KV vacuum high-voltage circuit breaker. The spring operating mechanism and the vacuum interrupter are arranged up and down, which is different from the plane layout mode in the prior art in which the spring operating mechanism is scattered. Compared with the original mechanism, the size is reduced by 60%, the number of parts is reduced by 50%, and the total weight is reduced by 30%. The 24KV vacuum high-voltage circuit breaker has the advantages of long service life, no need for maintenance, no pollution, no danger of explosion, low noise, and the like, and is more suitable for frequent operation and other harsh working conditions.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and in particular relates to a 24KV vacuum high-voltage circuit breaker with a small modular spring operating mechanism. Background technique [0002] High-voltage circuit breakers are responsible for the protection and control of overload and short-circuit of power equipment in high-voltage power supply and distribution systems. The spring operating mechanism in the existing 24KV high-voltage vacuum circuit breaker is installed in a distributed plane layout, and its structure is complex, with many parts and a large space, which makes the vacuum high-voltage circuit breaker light in weight. Therefore it is necessary to propose improvements. Contents of the invention [0003] The technical problem solved by the present invention is to provide a 24KV vacuum high voltage circuit breaker with a small modular spring operating mechanism. The present invention applies the VSH small mo...
