The heat-insulated enclosures of the Orion MK VO series are designed for installation into the internal space of devices that convert an optical image into a digital stream with subsequent transmission over cable networks and the Internet to playback devices for this signal. Housings make it possible to prevent the influence of various aggressive and hazardous working environments on equipment, including in places where the operating temperature is up to 200° C, as well as in the conditions of the possible presence of an explosive atmosphere.
A scope in ensuring protection, safety and control of technological processes of explosive and aggressive productions of oil, oil processing, petrochemical, gas, metallurgical and in other difficult and technological productions.
Heat-insulated enclosures Orion MK VO has a type of explosion proof “explosion proof enclosure “ d ”. Explosion protection marking PB Ex d I Mb X / 1Ex d IIС T6 Gb X according to GOST R IEC 60079-0-2011. The sign "X" in the marking means not to expose the light transmitting part to mechanical stress.
Heat-insulated enclosures Orion MK VO belong to explosion-proof electrical equipment of groups I, II, III according to GOST R IEC 60079-0-2011 and are intended for use in underground mines of mines, mines and their ground structures, as well as in explosive rooms, outdoor installations and dusty environments in in accordance with the established marking of explosion protection, the requirements of TR CU 012/2011, GOST R IEC 60079-14-2011 other regulatory documents that govern the use of electrical equipment in hazardous areas and in areas that are hazardous to ignition neniyu combustible dust.
Heat-insulated enclosures are designed to operate at ambient temperatures from minus 60 ° C to plus 50 ° C, the type of climatic performance is UHL1 according to GOST 15150-69. Atmospheric pressure from 84 to 106.7 kPa. The degree of protection of the shell is IP67 according to GOST 14254.
Protection against electric shock in accordance with GOST 12.2.007.0-75: class III / class I. The metal case has a protective earth and working insulation from current-carrying parts. At a supply voltage of 220V AC, protection class I, at a supply voltage up to 24V DC or AC, protection class III.
Heat-insulated enclosures are available in versions that differ in the case material, dimensions, supply voltage, the presence of infrared (IR) illumination.
Heat-insulated enclosures are supplied with cable glands of various versions:
Video cameras are completed with cable entries of the KV TU 3449-138-81888935-2016 series produced by “LLC Company SMD”. Connection thread for cable entries G1 / 2. Cable entries allow you to enter and output cables of circular cross section with a diameter of 6-12mm.
The heat-insulated enclosures Orion MK VO jacket is a sheath for installing electronic equipment into the housing, followed by installation in aggressive environments, as well as in places where there is a risk of leakage of explosive gases. In cases of using thermocovers at elevated temperatures, the design provides for water cooling to remove excess heat, reducing the effects of thermal radiation. With an increase in the rate of coolant pumping, heat removal from the sheath of the thermal housing increases, thereby reducing the effect of temperature on the electronics..
Heat-insulated enclosures Orion MK VO is an explosion-proof case with a type of explosion protection with an explosion-proof casing “d”. Explosion-proof shell made of stainless steel. The body is a hollow cylinder with a double wall with a distance of 10 mm, welded flanges, removable covers. The back cover of the shell is attached to the case with eight screws and has on the outside two fittings with an internal thread for installing cable glands, and on the opposite side, which is installed inside the case, a power board is mounted. Borosilicate glass with high heat resistance and mechanical damage are embedded in the viewing window on the front wall. On the outer side of the shell there are welded fittings to which the pipeline with the coolant is connected. To exclude the ingress of moisture and dust, rubber seals are used at the attachment points for removable body parts. A visor mounted on top of the case is also an element limiting adverse environmental conditions..
Orion MK VO is equipped with a bracket for mounting on a horizontal or vertical plane, as well as a cantilever bracket for mounting on a pipe.
