Lid;Bottom end-cover-free and cable protection pipe connection setting simultaneously, there are security risks;Lower part connecting part has protection flip lid or upward
Pushing cover, in debugging and maintenance, protection cap, which loosens, is easy to influence operation, while because with aluminum conductive cap, conductive protection cap is held
It is easily brushed up against by tool, the safety accident for leading to short circuit is easily caused to occur.
4) D scheme, is integrally able to satisfy every technical requirements, but due to being two large divisions's composition, more two parts connection dresses
It sets, overall stiffness and heat dissipation are slightly lower, and structure is relative complex, and manufacturing cost is higher, it has not been convenient to whole factory.
The present invention is compared with existing situation:
1) fan-free Switching Power Supply and terminal box integrated design are used, heat dissipation ventilation is strengthened, extends power supply
Bulk life time;End cap and cable protection pipe connection setting are arranged at bottom, eliminate security risk.
2) cover board 5 of 1 lower part of shell takes out structure using drop-down, and the lower mouth of boxboard 2 is stained with insulating film 2-6, enhances wiring
Tool is not easy to brush up against cover board 5 when the insulation of window, debugging and maintenance, avoids the security risk that may cause short circuit when tool operation
Occur.
3) for convenience of overhauling, respectively there are a lanyard holes on shell 1 and cover board 5, couple with rope, can prevent installation or
Cover board 5 is fallen when maintenance.
4) cover board 5 is fixed on shell 1 using briquetting 6, and when removing cover board 5 from and being fastened on shell 1 with screw, device to hole occurs
The case where position is difficult and easily falls screw generation, improves operating efficiency.
5) overall stiffness and thermal diffusivity are high, and structure is relatively easy, and manufacturing cost is lower, facilitates whole factory.
