Problems solved by technology

When using this desktop instrument, one person needs to detect inside the generator chamber, and the other person judges outside the generator chamber. Due to human subjective factors, there is often a problem that the detection and judgment are not synchronized. On the one hand, it affects the accuracy of the detection. low detection efficiency
In addition, the system is complex and bulky, and it is inconvenient to carry and detect.

Abstract

The invention relates to a detecting cart of iron core fault of a handhold type generator. The detecting cart is formed by improving on the basis of the prior art. The main improving point of the detecting cart of the iron core fault of the handhold type generator is as below: (1) a handle and wheels are added; (2) both sides of a chassis are symmetrically equipped with a pair of frame width adjusting rods; the frame width adjusting rods are respectively inserted to an insert hole of a fixing cross rod of a corresponding detecting coil and fixed by a screw; (3) magnets are respectively inlaid on the bottom face of the chassis and the bottom faces of a pair of detecting fixing cross rods. The detecting cart of the iron core fault of the handhold type generator has the beneficial effects of being convenient to use and capable of improving the detection accuracy and detection speed.

Description

technical field [0001] The invention relates to a hand-held generator iron core fault detection vehicle, which is suitable for large generators in power plants. Background technique [0002] Mechanical stress, electrical stress and environmental stress can lead to deterioration of the insulation between the generator stator core laminations. The fault current caused by the deterioration of the core insulation will generate hot spots, further accelerating the deterioration of the core. For this reason, during the manufacture and overhaul of the generator stator, the insulation condition of the stator core laminations must be tested. [0003] At present, there is only one foreign company that can produce the electromagnetic core detection system, which includes detection coils, displacement sensors, phase sensors, single-chip microcomputers, display screens and desktop hosts. When using this desktop instrument, one person needs to detect inside the generator chamber, and the...
