Description

The utility model relates to the field of power engineering, namely: to the structures of the operating current cabinets (SHOT), which is a set of equipment designed for use at electrical substations as an operating direct current system.

Operating current cabinets (SHOT) are designed for:

- receiving AC electrical energy and converting it into DC electrical energy;

- charging / recharging the battery;

- distribution of electrical energy through direct current circuits;

- power supply of the auxiliary direct current circuits from the modules operating on the integrated bus system, as well as from the storage battery (AB) in case of the loss of the input AC voltage.

The device can be used at power plants, transformer substations, distribution points.

From the information provided on the Internet at https://www.enelt.com/?id=187 (the main site address is https://www.enelt.com/) an operating current cabinet (SHOT) is known, manufactured by ENELT »Includes two charging and rectifying devices (ZVU) operating in parallel; DC load distribution panels; a rechargeable battery located in a battery cabinet or on racks.

Also, from the information provided on the Internet at https://www.enelt.com/?id=790 (main website address is https://www.enelt.com/), the advantages are known in the case of an LV switchgear (low-voltage complete device) with pull-out functional units:

- the use of pull-out functional blocks allows you to perform maintenance work on the elements of the low voltage switchgear without removing the voltage. Operation control and management are carried out without opening the doors. All controls are located on the front side of the ASSEMBLY. The presence of electromechanical interlocks prevents possible errors by operating personnel.

- it is possible to manufacture low-voltage switchgears of any configuration with various combinations of pull-out functional units and additional expansion of the structure by increasing distribution panels with new units. In addition, it is always possible to quickly modify the pull-out function block and thus quickly adapt it to new technical requirements.

- in addition to standard standard solutions, the design of pull-out functional units can be individually modified to meet the customer's non-standard requirements. The design of the drawers allows the use of equipment from any manufacturer, without reference to a specific brand.

Since the CWS is a low-voltage complete device, the above advantages also apply to CWS designs with pull-out functional blocks.

The disadvantage of the known design of low-voltage switchgear (manufactured by ENELT) with retractable functional units is that all roll-out functional units are separate independent structures with independent external panels, which makes it inconvenient to operate and maintain the known design. In addition, such a design complicates the design of the ASSEMBLY, prevents the possibility of adapting the ASSEMBLY to different types of equipment.

From the information provided on the Internet at http://srza.ru/uploads/catalog/shot_small.pdf, an operational direct current cabinet of the SHOT type produced by OOO Relay Protection Systems is known. The operating current cabinet consists of two cabinet-type metal structures, floor-standing, located side by side. In the left cabinet there is a charging and rectifier device, control and distribution devices for operating current, and in the right cabinet there is a storage battery. Control and measuring, light-signaling and switching equipment is located on the door of the left cabinet. Structurally, the SHOT cabinet is a prefabricated metal cabinet-type structure, consisting of two compartments, separated by a horizontal partition: charging and distributing and battery. The casing of the cabinet is made in floor-standing design. Structurally, the product provides free access to control elements, as well as ease of installation and dismantling. The upper compartment contains two rectifier modules, devices for monitoring, control and distribution of direct operating current, in the lower compartment there is a storage battery. The upper door of the cabinet serves as a front panel; it contains control and measuring, light-signaling and switching equipment. The input and output of the supply and outgoing lines of the SHOT is made through the sealed glands located at the bottom (top) of the cabinet. SHOT

The technical result achieved by the claimed utility model is an increase in ease of use and maintenance due to the possibility of removing for repair, observation or maintenance of equipment located inside the cabinet - equipment and batteries.

The technical result is achieved due to the fact that in an operating current cabinet containing a frame frame made of steel and made in the form of a parallelepiped, the internal space of the frame is divided into a section of charging and rectifier modules located in the upper part of the frame, a section of distribution equipment located in the middle parts of the frame, the battery section located in the lower part of the frame, the frame contains two side sides, front and front sides, the front side is equipped with a door covering all frame sections with ventilation grilles, according to the utility model, the cabinet in the lower section is equipped with roll-out shelves designed for placement batteries, while two opposite sides of the frame in the lower section are equipped with the first parallel horizontal U-shaped guides facing each other, each roll-out shelf for the battery is installed in the slots of the first U-shaped guides with the possibility movement along them, each shelf for the battery is equipped with a means of attaching the battery to the shelf, in the upper part of the frame there is a shelf for placing the charging and rectifier modules, in the middle section of the frame there is a mounting panel for switchgear, the mounting panel is made with an L-shaped transverse section, the outer surface of the horizontal section of the L-shaped mounting panel faces the front side of the frame and is equipped with a handle; on the free edge of the vertical section of the L-shaped mounting panel, runners are fixed, made in the form of strips placed in the second U-shaped guides, fixed parallel to each other above the other on one side of the frame in its middle section, the runners are placed in the said guides with the ability to move along them, through holes are made on the surface of the vertical section of the L-shaped mounting panel, designed to accommodate fasteners in them for fixing on the mounting panel of the switchgear.

The means for attaching the battery to the shelf can be made in the form of ties, which are two parallel threaded pins installed on top of the shelf in threaded holes, with the possibility of their exit to the opposite side of the shelf, the upper ends of the pins are placed in the holes made in the horizontal strip, and go outside the specified strip, at the ends of the studs there are nuts for tightening the studs after being placed in the space between the shelf and the horizontal strip of the battery.

The dimensions of the roll-out shelves and the mounting panel must be made taking into account their placement within the frame.

The shelf for placing the charging and rectifying devices can be made in the form of a box or basket.

In the declared operating current cabinet (SHOT), the internal space is divided into three zones (sections):

- zone (section) of charging and rectifier modules;

- zone (section) of distribution equipment;

- zone (section) of the storage battery.

The operating current cabinet is equipped with a touch panel that monitors and controls the entire installation. To activate the panel, you need to click on the screen anywhere in it. The touch control panel can be implemented on the basis of the well-known HVR EMS 2G controllers with a liquid crystal display.

The declared SHOT cabinet is a frame made of sheet steel.

The touch panel is located on a single outer door of the SHOT cabinet, equipped with ventilation holes / slots, as well as light-signaling elements.

Each battery is installed on a corresponding shelf located in the lower zone (section) of the cabinet so that no other equipment is located below the battery, thereby excluding the possibility of its damage in case of emergency damage to the shelf with the battery.

The body of the claimed cabinet SHOT is a frame frame made of steel. The frame forms a parallelepiped in space with two lateral sides, as well as a back and front side. The front side of the frame is closed by a door.

The shelf for the battery is withdrawable. For this, two opposite sides of the cabinet frame are provided with rigid, strong parallel U-shaped guides, forming a rigid structure with the frame. The said first U-shaped guides face each other with a groove in order to ensure that the shelf is placed in their grooves with the possibility of its movement along the said grooves from the back wall forward with the door open, which closes the cabinet from the front side.

Each battery shelf is equipped with means for attaching the battery to the shelf to exclude the possibility of spontaneous overturning of the battery when transporting the cabinet in a horizontal position. For example, the battery can be attached to the shelf by means of ties, which are two parallel threaded pins installed on top of the shelf in threaded holes, with the possibility of their exit to the opposite side of the shelf. The upper ends of the pins are placed in the holes made in the horizontal bar and go outside the said bar. The battery is placed in the space formed between the shelf and the tie, after installing the battery, the studs are tightened by means of nuts, ensuring the battery is fixed on the shelf.

Charging and rectifier modules (ZVU) are located in the upper zone (section) of the SHOT cabinet. The placement of the ZVU modules in the upper zone of the SHOT cabinet allows the subsequent use of the space between the batteries located in the lower zone of the SHOT cabinet and the ZVU in the most optimal way, taking into account the specific composition of the switchgear, thus adapting the design of the SHOT to specific conditions, specific needs of the consumer.

ZVU modules are independent devices and are installed on the upper shelf of the SHOT cabinet with the possibility of rigidly fixing their position on the shelf.

The shelf for the IED can be made in any way, for example, in the form of a basket with ventilation grilles, in the form of a box, etc.

Between the shelves of the battery and the ZVU in the SHOT cabinet there is a mounting panel for placing and fixing switchgear on it.

The mounting panel is L-shaped in cross-section. This form of the mounting panel allows you to conveniently attach the necessary equipment to it, as well as remove it for repair or maintenance, or monitor the state of the equipment.

The outer surface of the horizontal section of the L-shaped mounting panel faces outward towards the front, front side of the SHOT cabinet and is equipped with a handle for which the mounting panel can be rolled out of the cabinet.

The free edge of the vertical section of the L-shaped mounting panel is connected to two runners made in the form of strips, placed in the U-shaped guides, fixed parallel to each other on one side of the frame. The slats have the ability to move in the indicated guides.

To service the equipment fixed on the mounting panel, the L-shaped mounting panel is rolled out of the SHOT cabinet, holding the handle. The consumer has the possibility of full access to the switchgear, which will be located in the internal volume limited by the L-shaped structure of the mounting panel.

The assembled SHOT cabinet is closed with a door with a touch panel. Access to the equipment located in the SHOT cabinet is provided by rolling out the shelf with the battery for servicing or replacing the battery, by rolling it out along the guides of the mounting panel with the switchgear attached to it, or by removing the ZVU module from the upper shelf intended for it.

The side surface of the vertical section of the L-shaped mounting panel is provided with holes intended for fastening to the switchgear mounting panel.

The dimensions of the roll-out shelves and the mounting panel ensure their placement within the frame.

Ease of operation and maintenance in the claimed operating current cabinet is ensured due to the fact that all functional units (batteries, charging and rectifier modules, switchgear) can be installed on roll-out shelves or a retractable mounting panel.
