ЭМДВ – ХХХ Х5

• Э — device of the electrical drive control;
• МД — modified;
• В — explosion-proof;
• ХХХ — rated power of the electrical motor driven in kW;
• Х5 — climatic version and location category according to GOST 15150.

The devices explosion-proof enclosures are welded construction consisting of four sections: the network section, the control circuit section, the apparatus section and the power section.
The network section is designed for the power supply, main drive and auxiliary drives cables input. For this purpose it has two cable glands with the diameter of 63 mm and four cable glands with the diameter of 32 mm. There is an explosion-proof bulkhead between the network section and the control circuit section. The control circuit section consists of inlet compartment and МУВ module compartment, separated by a bulkhead with holes intended for laying of control circuits. There are communicating plugs mounted in each compartment to support laying of control circuits from apparatus section to control circuits section. There are also terminal blocks mounted in the control circuit section. The inlet compartment is designed for intrinsically safe circuits only. For cables input/output it has one cable gland with the diameter of 40 mm and one cable gland with the diameter of 32 mm. The inlet compartment is closed with bolted-type removable cover. The МУВ module compartment is designed for mounting the module of control and visualization and three control buttons. The МУВ module and buttons are placed to the rotary cover, which has a rectangular viewing window covered with a transparent polycarbonate for the МУВ module screen review.
The МУВ module compartment cover is mounted on hinges and is fixed to the casing with countersunk screws. The apparatus section contains the power disconnecting switch, contactor, power sources, control and protection apparatus. It is provided with a rectangular bolt cover with an outer flange mounted on the rotary hinges. The power section contains the frequency converter, input and output inductors. There is a bulkhead between the power section and the apparatus section with an opening for laying of control and power cables. The power section is provided with a rectangular bolt cover with an outer flange mounted on the rotary hinges. All ЭМДВ enclosures are equipped with a warning plate “Open after power supply disconnection”. The device enclosures are equipped with the external and the internal earthing clips.
The ЭМДВ devices of 160 kW and higher are supported with a separate liquid cooling unite (designed to work in the coal mines). This unit includes a pump, radiator, expansion tank and a fan. The liquid cooling device is connected to the ЭМДВ via two hoses.
Overall dimensions of ЭМДВ enclosures are given in drawing 1.
