Various electrical equipment such as breakers, electromagnetic switches, control relays, etc. are attached to the unit frame of the closed switchboard. These electrical devices are directly attached to the unit frame according to various specifications, and wiring between the electrical devices is performed on the surface side of the unit frame on which the electrical devices are attached. The wiring is appropriately bundled and arranged to give it a good appearance. However, this structure had the following problems. (a) There is insufficient shielding between the electrical equipment on the front side of the unit frame and the side facing the contacts and busbars on the back side, making connected wires and equipment susceptible to damage by arcs that occur during failures. In addition, Japanese Utility Model Application Publication No. 61-144703 discloses an electrical equipment control panel in which a chassis with a hat-shaped cross section is attached to a main body frame, and a vertically penetrating space is formed between the chassis and the main body frame. It has been done. When this structure is applied to the unit frame of a closed switchboard, the shielding between the electrical equipment and the contacts and busbars on the back side is insufficient, so the arc generated at the time of a failure leaks from the vertically penetrating space. It spreads, and connecting wires and equipment are susceptible to damage. Therefore, there is a problem in applying it to the unit frame of a closed switchboard. (b) During manufacturing, the work efficiency is not good because the connections and wiring between electrical equipment must be carried out by one worker at the work site while adjusting the dimensions. (c) Because the wiring and bundling methods differ slightly depending on the operator, variations in product appearance tend to occur. (d) If the type or arrangement of electrical equipment changes due to a change in the specifications of the closed switchboard, and the position or number of mounting holes for mounting them changes, the unit frame will need to be processed and manufactured differently each time. Yes, inventory management is difficult.
本発明の第１の目的は、電気機器と接触子や母

A first object of the present invention is to shield electrical equipment and contacts and busbars so that connecting wires and equipment are less likely to be damaged even if an arc occurs in the event of a failure. A second purpose is to improve work efficiency by making it possible to separate labor in connection and wiring processing during manufacturing, and to eliminate variations in the appearance of wiring and bundling of products. Furthermore, the third objective is to allow the unit frame to be shared while ensuring sufficient shielding between each device and the contact side, so that even if specifications change, it can be handled with the standard unit frame, and the inventory of unit frames can be reduced. The purpose is to make management easier.

The present invention has the above configuration and has the following effects. (a) A double partition wall consisting of the unit frame body and the mounting frame will be installed between the control equipment and the contacts and bus bars, and the wiring accommodation space on the back side of the mounting frame is almost closed on all sides. Since the wires are in a stable state, they are unlikely to become a path for arcs that occur during failures, thereby preventing damage to connected wires and equipment. (b) In the past, all equipment was attached directly to the unit frame body, and wiring work was also done at that time, making it impossible to divide the work and resulting in poor work efficiency. In contrast, in the present invention, the equipment is attached to the unit frame body and the mounting frame, and the mounting frame is further attached to the unit frame body. Therefore, equipment installation and wiring work can be carried out on both the unit frame body and the mounting frame. Since work can be divided in this way, work efficiency is improved and production efficiency is improved. (c) Wiring between control devices attached to the mounting frame is housed in a wiring accommodation space between the unit frame body and the mounting frame and does not come out onto the surface. Therefore, there is no need to bundle and organize the wiring, which saves time and effort. Furthermore, there is no inconvenience such as variations in the appearance of the product due to differences in the broken lines and bundling methods depending on the operator. (d) Wiring between control devices is housed in the space between the unit frame body and the mounting frame, so there is more space on the front side. Therefore, more control devices can be incorporated, and various specifications can be accommodated. (e) The main body of the unit frame to which standard equipment is attached can be shared, and the mounting frame to which control equipment that changes depending on the specifications is attached can also be shared if the mounting holes etc. are set to accommodate the maximum number of equipment used. Therefore, the unit frame as a whole can be standardized, and inventory management etc. are easy.
