[Previous technology] In the Ba-Yan / Zhang device mechanism, the main switchgears are divided by connecting j: shu or a partition plate made of insulation, and several locked ones are called inside the frame. It is a compartment that divides the space (CD-plus). The purpose of the division is to protect the operation and maintenance inspectors to pick up the station & the charging department and the protection of foreign objects. It is produced inside the mechanism of the device and is used to limit the scope of the impact. This kind of partition space-r line (bus) partition space, circuit breaker partition, and load side cable partition space. Contains :::: Although the electrical equipment in the frame of the closing mechanism is a package, the main circuit machine constituting the main circuit of the circuit breaker and the switching device connected to the main bus line is crying. Controllers for road machines, but these electrical machines: Installed in the frame after the control and control of these main electrical bodies are completed :: installed: = set: the frame wiring operation has been performed in a narrower space ·, 4. The weight of such an assembler is also large, so the operation is difficult. This: And because the electrical machine assembly work is completed, it needs to be installed in the main circuit machine for a long time. (For example, refer to the spring operation 'so a bulletin is needed). Inch date. No. 53-74254. Therefore, the object of the present invention is to obtain a switchgear mechanism that can be easily assembled. , Operation and wiring work 314821 6 2 volumes 427172 L Summary of content] (Problems to be solved by the invention) Door two: The switchgear mechanism according to the present invention is provided with: A circuit machine and an electric machine that controls the two main circuit machines; and a frame housing the electric machines, ... the above-mentioned frame system has: the main circuit machine port to house the main circuit machine, and the control The controllers form an independent lockout and separate the controller room of the main circuit machine room and the ompartment controller room.
