UNIT WITH BRUSH HOLDER BRUSH HOLDER With pneumatic cylinder SINGLE ACTION UNITED COMMON COMMON ducts with pressure regulator, MACHINE PREPARATION AIR receiver, a compressed air source

摘要

1. The object of the utility model: the brush holder unit which is mounted in a housing brush holders with pneumatic cylinders single-acting with a magnet, a magnetic sensor, and the cylinders are connected to a duct which is connected to a pressure regulator with a scale indicating the level of pressure, air handling unit, the receiver, the compressed air source, control panel.; 2. Scope: The invention relates to the field of electrical engineering.; 3. The essence of the utility model: the brush holder unit contains two or more brush holders, brush holders consists of a housing unit, pos. 1, current collecting plate, pos. 2 to which the fixed brush holders, pos. 3, with a single-acting pneumatic cylinders with magnets, magnetic sensors, rods which act on the electro pos. 4. Each pneumatic cylinder tube brush holders, pos. 6, is connected to the duct, pos. 5 wherein including in each air cylinder via a pressure regulator, pos. 10, air handling unit, pos. 9 receiver, pos. 12, which supports the required constant pressure (pressing force) providing a constant pressure on the electro pos. 4 regardless of its wear.; Pressure adjustment pressure regulator, pos. 9, provides a constant, defined pressing force on each electro depending on the type of device, material, etc.; In applying the brush holders, pos. 3, with a single-acting pneumatic cylinders with a magnet, the magnetic sensor through the remote control key. 13, to determine the wear of each electro and pressure gauge, pos. 11 will provide visual monitoring of the pressure on the each electro.; The system providing compressed air for air preparation unit is outside of the electrical machine and comprises a source of compressed air, pos. 8, air preparation unit, pos. 9 which is provided with a pressure regulator with a scale display, pos. 10, a pressure gauge, pos. 11. guest receiver key to maintain a certain, constant air pressure in the system of the brush holder unit. 12.; Repair and maintenance of the brush holder unit amounts to replacing worn electrobrushes, pos. 4, the replacement electrobrushes in the brush holder is made without stopping the electric machine, which is necessary to disconnect the tube, pos. 6, removing it from the fitting with collet clamp, pos. 7, of the duct, pos. 5. Air pressure loss is insignificant and compensated pressure regulator, pos. 10, receiver, pos. 12. hand pressure, to release a pencil case made of insulating material with electro worn by locking the clamping spring, disconnecting the brush holder from the housing. Replace electro and make installation of the brush holder in the reverse order.; Thus, the technical result which is reached when implementing the proposed apparatus brush holder the housing is mounted brush holders with pneumatic cylinders single-acting air duct connected to each pnevmotsilidrom, a common pressure regulator, air handling unit, the receiver, the compressed air source provide a constant pressing force on each Electrobrushes each brush holder regardless of the wear and tear, reduces vibration of the brush holder device, mechanical wear, arcing, electric ktrichesky wear stabilizes the friction coefficient, deformation electrobrushes provides maximum wear electrobrushes thereby prolongs work electrobrushes and the sliding electrical contact (collector slip rings), and the use control of the retaining a constant depression force on each electro apparatus brush holders and wear provide reliability quality work at lower costs for maintenance and repair, security appliances brush holder system and the electrical machine elom.
