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...
