MK-AB is intended for electrical substations of 6-500 kV with direct operating current and switches that require an independent power source to ensure the switching capacity.
MK-AB is a device consisting of one or several modular blocks, joined into a single room, in which electric heating, lighting, ventilation are performed, and racks for accumulators are installed.
The type of MK-AB is determined by the terms of reference depending on the type of batteries and their quantity.
Batteries are installed on special racks fixed to the base of the blocks (batteries are not included in the MK-AB delivery set).
The floor in the AB and acid room is covered with acid-resistant tiles. The ceiling is smooth. Walls, doors and ceiling are painted with acid resistant paint. All electrics are laid in pipes.
Power cables are entered through the openings in the floor of the room.
Working and emergency lighting of the MK-AB battery room is made with explosion-proof LED lamps.
Heating is carried out by explosion-proof electric heaters. Control — automatic from a temperature sensor located inside the battery.
The MK-AB room is equipped with a stationary supply and exhaust ventilation system with a 100% reserve, the supply ventilation is equipped with an electric heater for heating the air. The hood is provided by explosion-proof exhaust fans. Additionally, natural ventilation with a single air exchange is provided. To maintain a constant temperature in the summer, it is possible to install a central air conditioner in the ventilation system.
The security and fire alarm system is based on magnetic contact sensors installed on the gates and doors of the building. When performing an access control system, the doors and gates are additionally equipped with an electromagnetic lock. The premises are equipped with smoke and heat detectors, glass break detectors, volumetric detectors, exit buttons and a manual call point. Outside the building, a «Siren» sound notification and a reader for disarming are installed. A fire alarm panel is provided with a control panel installed inside, a control panel, a switching device. The sensors are connected to the security and fire alarm devices with a fire-resistant cable.
At the request of the Customer, a video surveillance system based on stationary cameras and a video surveillance cabinet with installed equipment for storing and transmitting data is mounted in the building.
