Description

Fixed type phase sequence display cascade base type intelligent power distribution module

The utility model relates to a power system, in particular to a fixed intelligent power distribution module with phase sequence display cascaded base.

Background technique

There are several types of market distribution methods:

1. Fixed installation and distribution, the implementation method is to distribute the components such as switch components, acquisition and measurement devices, measuring devices, control devices and signal indicators in the screen rejection.

Fixed installation and distribution have the following drawbacks:

It is uncertain, it is not easy to standardize production, and many primary and secondary lines are bundled together, and maintenance is very inconvenient.

The installation workload is large, the production is difficult, the randomness is large, and the product quality is difficult to maintain consistency. There are not only the primary line, the secondary line, and the communication line between the switch components and the device, but also the open line installation, which affects the appearance.

2. Drawer type "semi-modular" power distribution mode, the implementation method is to concentrate the switch components and the like in one drawer, and use the primary and secondary plug-in plug-in power distribution, that is to say the switch components and the incoming busbars. The outgoing cable can be separated, which facilitates the replacement and maintenance of the switching components.

Drawer type "semi-modular" power distribution has the following drawbacks:

The production of drawers is basically pure manual operation, the degree of standardization is low, and the secondary lines after group screens are also 4 messy, affecting the appearance and being difficult to maintain. The group screen is cumbersome, and each drawer needs to be equipped with corresponding guide rails, and there is a layer between the drawer and the drawer to be isolated and fixed. It is a bit hard to install.

Drawer type "semi-modular" Power distribution mode has a low single screen capacity and takes up a large amount of screen rejection space.

3. Fixed modular power distribution, the implementation method is to combine the switch, sensor, acquisition, control and measurement devices together to properly distribute the functions of each part, which can realize the independent maintenance and replacement of each function sub-module, while reducing the volume and increasing Capacity, high degree of production standardization, high product consistency and stable quality.

Fixed modular power distribution has the following drawbacks:

Although the fixed modular power distribution has high standardization and convenient production and maintenance, it is difficult to process. It varies with the brand and specifications of the switch. The module has more specifications and a larger investment. Communication lines are not standardized and vary from project to project, affecting the process and reducing operational safety.
