Disconnection of the circuit: how to execute yourself

The contact device is two metal pins of various lengths fixed on the disk of insulating material. The pins have tips that serve to adjust their length. Electrically, the pins are isolated from each other and are attached to different veins of one end of the wire, the other end of which is fixed on the drum of the primary device. To protect the places of joining the wire to the pins, a rubber casing is provided. In construction, you may need wooden windows to order which you can inexpensively here: wooden windows. The primary device is mounted in a cast -iron case 1, on the wall of which an electric drive is installed, consisting of an electric motor 2 and gearbox 3. The gearbox through automatic fist 4 is associated with a shaft of 5 drum 6, on which there are grooves for laying wires. In the upper part of the case, the wire 8 and the final circuit breakers 9 are mounted on two guides. On the right side of the body, a block of village of village 10, consisting of two village-sensors equipped with a rough scales (25 m) with a division of 10 cm and accurate reference (1 m) with a 2 cm division price. Impulsi 11, consisting of a fist and a contact group, provides the issuance of a hundred pulses in one revolution of the drum. At the end of the shaft 5, a backcrowing device 12 with brushes is fixed, designed for the electrical connection of the contact device with the control circuit. Block of village sensors, a backdrop device and pulses sensor are located in a dustproof compartment having a door 13 with an observation glass. The secondary device is mounted in a welded dust -proof shield body, which has a door glass door. Inside the case, a double-in-worn agricultural receiver is installed, equipped with a “centimeter” and “meter” arrows and the corresponding scale. A fist is fixed on the “meter” axis, which closes the contact group at the time of working out the task. On the front panel of the device there are a flywheel, with which the contact group is installed in the position corresponding to the task, the buttons of turning on and disconnecting the level.
