のが一般的である。The closed switchboard houses electrical equipment, main circuit equipment such as current transformers, and the entire main circuit, including the conductors and main circuit busbars that connect these equipment, the main circuit, the main body frame, unit partition barriers, and disconnectors. Each unit is closed by a section, door, etc. to form a distribution box. The main circuit is provided with a current transformer for protection and measurement of the main circuit equipment and the system. A single current transformer or a plurality of current transformers are arranged depending on the system for protection and measurement of the grid, and the shape and size of the current transformer generally differ depending on the capacity of the circuit.

た。Conventionally, a plurality of these current transformers of irregular shapes were attached directly to the main body frame, which had the drawback of requiring processing of the main body frame each time, hindering standardization and requiring a large number of man-hours. Furthermore, the mounting position of the insulator that supports and fixes the primary conductor passing through the current transformer was selected according to the shape of the current transformer, and separate metal fittings were provided, which increased the number of parts and required them to be installed in a narrow box. Because it is assembled inside the body, work efficiency is poor, and therefore the number of assembly steps increases, making it expensive.

１１を設置し、次の様に構成する。A distribution box 3 with a door 2 attached to one end includes a breaker chamber 7 configured with a breaker 4, a disconnecting section 5, and a partition plate 6, a busbar chamber 10 configured with a busbar 8 and a connecting conductor 9,
Each unit of the conductor chamber 14, which is composed of the current transformer 11, the primary conductor 12, and the cable head 13, is formed separately.
Ru. - A current transformer 11 is installed on the secondary conductor 12 for circuit protection and measurement, and is configured as follows.

定するように形成する。As shown in FIG. 2, the three-phase current transformers 11 adjacent to each other are provided with bent portions 16 by bending both ends of the mounting bracket 15.
It is housed inside this bent part 16, and an insulator 17 is provided on the upper surface of the bent part 16 to support and fix the primary conductor 12 passing through it.
即ち、三相の変流器１１を貫通する一次導体１２と共に
一体構造に出来る。That is, it can be integrated with the primary conductor 12 passing through the three-phase current transformer 11.

変流器１１の変化に即対応でき標準化が可能となる。This mounting bracket 15 has an increased section modulus by providing the entire bent portion 16, and therefore has increased mechanical strength and can withstand a large short-circuit current. Furthermore, a space is provided inside the bent portion 16 in which a plurality of current transformers 11 can be stored, and the length t of the primary conductor 12 passing through and the height hl of the lower surface of the mounting bracket 15 are made constant. If so, even if the rating and capacity of the current transformer change, will the dimensions of the main body frame of distribution box 3 be the same? without changing
It is possible to immediately respond to changes in the current transformer 11 and to standardize it.
