Distribution type two-stage distribution box

Abstract

The invention discloses a distribution type two-stage distribution box comprising one two-stage distribution box (11) and multiple distribution box sub-units (12). The first distribution box sub-unit (12) is connected with the two-stage distribution box (11) via a cable, and the second distribution box sub-unit (12) is connected with the first distribution box sub-unit (12) via the cable. Similarly, other multiple distribution box sub-units (12) are connected to form a string. Each distribution box sub-unit (12) comprises a lighting box (10) which is respectively provided with a wiring terminal (2), a zero row (3), a 32A 3P air switch (4), a 25A 2P electric leakage protector (5), a 10A single-P air switch (6), a ground row (7), a 380V aviation socket (8) and a 220V aviation socket (9). According to the distribution type two-stage distribution box, temporary electricity utilization of a construction site is reasonable in arrangement and safe in application so that the construction site is more standard and neater.

Description

technical field [0001] The invention relates to a split point type secondary distribution box. Background technique [0002] In our decoration project, with the advancement of science and technology, mechanical appliances have completely replaced the traditional manual operation, resulting in many and disordered cables on the construction site; especially in hotel decoration projects, the width of the aisle on the standard room floor is generally two meters On the left and right, secondary electric boxes and cables are placed on the aisle, causing the aisle to be blocked and messy, especially the cables must be in the form of poles. At the construction site, the layout of the power supply has become one of the biggest hidden dangers affecting the safety and civilization of the project. [0003] At present, the centralized secondary distribution box is used for construction electricity on the construction site. It has the following disadvantages: 1. The electrical box is lar...

Problems solved by technology

[0003] At present, the centralized secondary distribution box is used for construction electricity on the construction site. It has the following disadvantages: 1. The electrical box is large in size and has high requirements for cable erection. It is usually erected with poles, resulting in aisle poles and The cable layout is staggered, which takes up a lot of construction work space; 2. It is inevitable that the power distribution box will be repeatedly shifted during construction, which will damage the power box itself and pose a safety hazard; 3. In the past, the power box relied on three-level box connection Electric tools are used for switching after the cable is out. The process of multiple switching is insufficient for the protection of the cable and leakage; 4. The aisle wires and cables are laid along the ground, and the wire skin is easy to age, damage, and poor insulation.
