Description
Technical field
The utility model belongs to smelter generator detection device technical field, particularly relates to a kind of generator ground detection device.
Background technology
The principle of work of generator ground detection device is the positive and negative lead wires that rectifying disc draws rotor windings, and positive and negative lead wires is connected on slip ring, and the slip ring of rotation becomes path with fixing conductive carbon scopiform, is carried out the insulation against ground of detection rotor by the voltage detecting carbon brush.There is a lot of shortcoming in this ground detection device: carbon brush trembles, and carbon brush surface of contact forms air film, and the reasons such as collector ring wearing and tearing are uneven, carbon brush is lax, unit vibration all can cause; Can be there is jam phenomenon in carbon brush, as can not be up and down, must not wave in brush carrier, will cause field voltage loss, earthing detection false alarm; Carbon brush and lead-in wire, be connected loosen between lead-in wire with terminal, all can cause lead-in wire broken string, shell encountered by lead-in wire, causes generator excitation one point earth; Carbon brush abrasion aggravates, and brush block edge is once peel off, and the shunting out of trim of carbon brush, carbon brush generates heat, wearing and tearing aggravation.In order to overcome the above problems, special this generator ground detection device of invention.
Summary of the invention
The purpose of this utility model is that as generator excitation one point earth, carbon brush trembles, and carbon brush abrasion aggravation etc., provide a kind of generator ground detection device in order to solve generator grounding carbon brush detection failure.Realizing the technical scheme that object of the present invention takes is: a kind of generator ground detection device, include the first conductive plastics disk, second conductive plastics disk and outrigger shaft, first conductive plastics disk is positive pole, second conductive plastics disk is negative pole, it is characterized in that: coordinate with generator and be provided with terminal box, terminal box utilizes the first set bolt, second set bolt, 3rd set bolt and the 4th set bolt are fixed on electric generator casing, the first spring conducting probe and the 3rd spring conducting probe is provided with between terminal box and the first conductive plastics disk, the 5th spring conducting probe is provided with between terminal box and the second conductive plastics disk, first spring conducting probe, 3rd spring conducting probe and the first conductive plastics disk Elastic Contact, second spring conducting probe and the second conductive plastics disk Elastic Contact, the first described spring conducting probe is connected with the 3rd spring conducting probe and connects with external terminal, second spring conducting probe connects with external terminal.
The utility model is according to the interaction principle of power, the conductive plastics disk rotated is connected with fixing spring conducting probe by generator ground detection device, the pressure of conducting probe and conductive plastics disk can be adjusted by adjusting nut, make conducting probe and conductive disc compact siro spinning technology.The advantages such as this apparatus design is simple, easy to maintenance, investment is very little, bring notable results, are applied on generator by this complete equipment, avoid the problems such as carbon brush lead wire breaks, lead-in wire touches shell, carbon brush abrasion is serious.
