Description

A dual ATS power supply mutual switching power distribution cabinet

technical field

The utility model relates to the field of power distribution cabinets, and more particularly, the utility model relates to a power distribution cabinet with dual ATS power sources for mutual switching.

Background technique

For some important loads, in order to ensure the reliability of their power supply, two power sources are usually used to power them, one is used as a common power supply, and the other is used as a backup power supply, also called an emergency power supply. The voltage levels and properties of the two power supplies are the same. , The difference is that the power supplies of the two circuits come from different and independent power distribution systems. When the power supply is normal, the electrical equipment uses the common power supply. When the common power supply is cut off due to a fault, the circuit needs to be quickly switched to the backup power supply. The backup power supply is automatically switched in in a very short period of time, thereby ensuring the continuity of the power supply of electrical equipment. As a result, automatic transfer switch (ATS) devices are widely used today in power distribution systems for powering critical loads.

However, the hidden danger of single-point ATS device failure still exists. If the single-point ATS fails to be found in time, it is likely that the consequences of power failure of important loads will occur, resulting in major property losses and social impacts.

Utility model content

In view of the problems in the prior art, the embodiment of the present invention provides a dual ATS power supply mutual switching power distribution cabinet, through the cooperation of the two ATS and the output switch, the hidden trouble of single-point ATS failure is eliminated, and the power supply reliability of the important load is improved. , in order to solve the problems raised in the above background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a dual ATS power supply mutual switching power distribution cabinet, comprising a cabinet body, an AC incoming line switch, an ATS device, a lightning protection module, an LCD multi-function digital display meter, and an AC transformer. , AC output switch, copper bar.

The middle of the cabinet is provided with two side-by-side ATS devices; the ATS devices are connected to the LCD multi-function digital display screen through an AC transformer.

In a preferred embodiment, the upper part of the cabinet is provided with four AC incoming line switches.

In a preferred embodiment, the lower part of the cabinet is provided with 6 of the AC output switches.

In a preferred embodiment, the lightning protection module is located behind the cabinet.

In a preferred embodiment, the LCD multi-function digital display is located in front of the cabinet.

In a preferred embodiment, the LCD multi-function digital display meter is connected to the AC incoming switch, the ATS device, the AC output switch and the lightning protection module through the AC transformer, and the The LCD multi-function digital display meter can display all switch states, voltage, current and power values in the cabinet.

In a preferred embodiment, the LCD multi-function digital display meter can transmit data to an external device through RS485 or RJ45 protocol.

In a preferred embodiment, the copper bar (8) is located at the lower part of the cabinet (1).

The dual ATS power supply mutual power distribution cabinet provided by the utility model includes a cabinet body, an AC incoming line switch, an ATS device, a lightning protection module, an LCD multi-function digital display meter, an AC transformer, an AC output switch, and a copper bar. By configuring two ATS devices, the power supply reliability of the power supply load of the power distribution cabinet is improved. When the single-channel power supply loses power, the ATS can change the power supply to the backup power supply to ensure the power supply of the load; when the single-channel power supply loses power, the single-channel power supply The ATS also fails, and another ATS can continue to supply power to the load, thereby avoiding the hidden danger of single-point ATS failure and improving the power supply reliability of important loads.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Figure 1 is a dual ATS power supply mutual power distribution cabinet, including cabinet 1, AC incoming switch 2, ATS 3 device, lightning protection module 4, LCD multi-function digital display meter 5, AC transformer 6, AC output switch 7. Copper row 8.

The inner cavity of the cabinet is provided with an AC incoming line switch, an ATS device, a lightning protection module, and an AC output switch, and an LCD multi-function digital display meter is arranged above the front side of the cabinet. Optionally, in the cabinet, the AC incoming line switches are distributed above the dual ATSs, the two ATSs are arranged side by side, and the AC output switches are distributed below the dual ATSs.

In the utility model example shown in Figure 2, the ATSs all have short-circuit and overload protection functions, over-voltage, under-voltage, phase loss automatic conversion functions and intelligent alarm functions. The first input terminal and the second input terminal of ATS1 are respectively connected to the two AC incoming switches on the left, the first input terminal and the second input terminal of ATS2 are respectively connected to the two AC incoming switches on the right, and the three AC output switches on the left It is connected to the ATS1 output copper bar, and the three AC output switches on the right are connected to the ATS2 output copper bar.

The LCD multi-function digital display meter collects the electrical status of the AC incoming switch, ATS, lightning protection module, and AC output switch through the AC transformer, and can transmit the data to external devices through the RS485 or RJ45 protocol.
