The switchboard in the explosion-proof version of PKV Orion MK SK is intended for uniting remote network devices into one or several network segments in the conditions of the possible presence of an explosive atmosphere. The switch allows the remote device to transmit electrical energy to each port up to 30W along with data through a standard twisted pair over a distance of up to 250m, and also to build distributed networks. The switch simultaneously supports data flows between all of its high-speed data ports..
The switchboard is manufactured on the basis of an explosion-proof PKV control station with an explosion protection marking of 1Ex d IIB T6 ... T4. This equipment is available in two versions, differing in the number of network ports with PoE support: PKV Orion MK SK-4, PKV Orion MK SK-8.
Taking into account the installed heating plate inside the shell, the switch can operate at an ambient temperature of minus 60 to plus 60 ° C and a relative humidity of 90% at a temperature of 40 ° C without moisture condensation. The degree of protection against dust and moisture penetration in accordance with GOST 14254 IP66. The type of climatic performance is UHL1 according to GOST 15150-69, type II atmosphere according to GOST 15150. Altitude - no more than 4300m. The switchboard corresponds to class I protection against electric shock according to GOST 12.2.007.0-75.
The switch belongs to electrical equipment of group II according to GOST 31610.0-2014 and is intended for use in hazardous areas, rooms and outdoor installations in accordance with the explosion protection marking "1Ex d IIB T6 ... T4 Gb" and GOST IEC 60079-10-1-2011. The equipment can be used in hazardous areas of class 1 and 2 according to GOST IEC 60079-10-1-2011. Environment may contain explosive mixtures of gases and vapors with air of category IIA, IIB.
The switchboard is completed with explosion-proof cable entries of the KV TU 344995-138-81888935-2016 series produced by LLC “SMD Company”.
The design of the network enclosure of the explosion-proof PKV Orion MK SK switchboard is a separate explosion-proof enclosure that meets the requirements of GOST 31610.0-2014 and GOST IEC 60079-1-2011, consisting of a case, a rubber sealing ring of the cover. The lid is attached to the body with pivoting hinges and hermetically pressed against it with screws. The hinges connecting the lid and case are removable, so the lid can be completely detached from the case. The internal space of the flameproof enclosure allows optimal and convenient installation and maintenance for the internal components. The switch with the power supply unit is installed on the circuit board and is rigidly fastened with screws. Cables are supplied by explosion-proof cable glands, which, depending on the customer’s wishes, can be located on either side of the case, but also have a standard design. A heating plate with a thermostat is installed on one of the walls inside the shell, which allows you to maintain the optimum operating temperature for operation of the equipment mounted inside. The thermostat has a temperature control element that allows you to increase or decrease the temperature inside the shell. To reduce the rapid cooling plates are provided from izolona. On the outer side around the perimeter of the cover, spring washers are installed, pressing them with screws thereby preventing the unscrewing itself. Sealing two diagonal screws provides unauthorized access to the internal cavity.
Depending on the configuration, the switch can connect up to eight IP devices (cameras, telephones) to itself, allowing you to create a local network and transfer data to the operator’s post. In the switch design, there are PoE ports, which provide power to the remote device with a single cable, transmit the signal, as well as control the rotation of the camera to the desired angle. The CCTV-Default mode switch is located on the side wall of the switch, allowing you to increase the data transfer distance up to 250 meters. PoE ports reduce the cost of materials during installation, respectively, reduce the cost of installation, maintenance and thereby save time.
An explosion-proof switch connects to IP devices in this case IP cameras. Cameras can be located on the periphery of the protected object or in places of technological processes. The switch allows you to combine remote devices into one network and output data to the operator's post with high speed and clarity, allowing you to track violations in technological processes at hazardous facilities and detect illegal intrusion into the territory of the object. Each connected device has an individual MAC address, fixing this address the switch assigns a separate port, thereby connecting the devices into a separate network.
