AVR - automatic input reserve cabinet (box)

AVR

ATS boxes (cabinets) are designed for instant restoration of power supply to consumers by automatically connecting a backup power source when the main source is disconnected.

Automatic Input Reserve Boxes (Cabinets) Y(Sh)AVR

Purpose:

The boxes (cabinets) Ya(Sh)AVR are designed for instant restoration of power supply to consumers by automatically connecting a backup power source when the main source is disconnected.
The nominal current of the AVR cabinets is from 5 A to 1000 A. The body is made of steel with a powder paint coating. The automatic input reserve cabinets have a service life of 20 years. The warranty period is 12 months from the date of commissioning.

AVR cabinet design:

In terms of design, the box (cabinet) is a metal cabinet with equipment installed inside. Electrical devices are installed on the box's mounting panel. Light signaling fittings are installed on the door. Input and output of wires is possible from above and below through glands.

Specifications:

Thanks to the ATS cabinet, it becomes possible to switch power from the main line that has a fault to the spare line. Such equipment is indispensable for many offices and production facilities.

Because even a short-term power outage can have undesirable consequences. Malfunctions in computer and other devices can become the basis for stopping production for many hours.

In order to minimize unexpected situations, ATS cabinets automatically switch to backup power when the voltage on the main line drops.

Redirection is carried out even before the main line is disconnected, which ensures the supply of voltage without interference.
Modern ATS cabinets and their scope of use

Any ATS cabinet is designed directly to restore the power supply of the electrical network by connecting an additional source of energy if the working power source stops, which can lead to malfunctions in the operation of the equipment. After the connection to the main power supply is restored, the ATS cabinet switches to the circuit that was before the emergency power supply in automatic mode.

Features of these devices:

The casing of such equipment is presented in a floor or wall-mounted version. In the lower and upper parts of the case there are special loops designed to attach cabinets to the plane.
The output and input of outgoing and power supply lines is carried out by means of special glands. They are located at the bottom and top of the cabinet. The door is considered as a front panel. On the door there is a special light signal control and measuring equipment. As a rule, the price of the AVR cabinet is quite acceptable.

The structure of the conventional designation of the Y(SH)AVR:

The main tasks of the devices:

• implementation of voltage control directly in the circuits of the spare and main source;
• conducting control and changing the alternation of each phase;
• implementation of comparison of power resources. It is precisely due to this function that it becomes possible to comply with the main parameters and promptly restore the pre-emergency power supply;
• visual control of the occurrence of all malfunctions and failures in operation.

Types of equipment:

The ATS cabinets are divided according to such important properties as:

• the type of device on which the cabinet operates (contactless and switching);
• equipment operation algorithm (non-priority and priority).

Each ATS cabinet with a switching device is cheaper and simpler than options with a contactless device. In addition, they do not consume so many resources, and they are less susceptible to heating.
The priority scheme of operation is the presence of only one input for the so-called most important power source in the ATS cabinet. Non-priority devices are used in places where the main source of backup power is a network with a constant voltage level.
