Network explosion-proof router PKV Orion MK WiFi

The explosion-proof router PKV Orion MK WiFi is designed to integrate IP devices into a single network with the ability to exchange data between them and organize a high-speed, secure Internet connection in the event of the presence of an explosive atmosphere. This equipment is manufactured on the basis of the control station of an explosion-proof PKV with explosion protection marking 1Ex d IIB T6 ... T4.

Taking into account the installed heating plate inside the shell, the router 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 design is UHL1 according to GOST 15150-69, type II atmosphere according to GOST 15150. Altitude at sea level is not more than 4300m. The router complies with Class I protection against electric shock according to GOST 12.2.007.0-75.

The router 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. The environment may contain explosive mixtures of gases and vapors with air of category IIA, IIB.

The router is equipped with explosion-proof cable entries of the KV series TU 344995-138-81888935-2016 produced by LLC “Company SMD”.

Design

An explosion-proof router allows you to analyze data, determine addresses and choose a route based on the information received, creating local networks using Wi-Fi. The operability is determined by sending a signal to the connected devices on the network, which makes it possible to determine the operability and to seek updating of all connected devices. One of the advantages of this network is the low cost of installation compared with the SCS, reduced maintenance costs, reliability, high speed of installation.

The shell design of the PKV Orion MK WiFi router is a separate flame-tight enclosure that complies with the requirements of GOST 31610.0-2014 and GOST IEC 60079-1-2011, consisting of a housing, a rubber o-ring cover. The cover is attached to the body with the help of pivoting hinges and hermetically pressed to it with screws. The hinges connecting the cover and the case are removable, so the cover can be completely detached from the case. The internal space of the flameproof enclosure makes it possible to accommodate internal components in an optimum and convenient way for installation and maintenance. The router 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.
