Problems solved by technology
Among them, the detection probe is a metal part, and the probability of aging and failure is extremely small; the secondary instrument is a modular component composed of electronic components, and the aging failure will gradually increase with time. At present, the detection device has reached the service life (80,000 hours). The country of origin of the equipment has been discontinued, and it is difficult to find alternative products that meet the technical parameters and have the same interface in the domestic and foreign markets

The invention, which belongs to the technical field of measurement, in particular relates to a detection device of equipment dielectric leakage. The detection device is composed of a power supply module, an inverted input terminal module, a non-inverted input terminal module, a voltage comparison module, an alarm output module, an anti-differential mode interference module, and a hysteresis module. The interface of the device can be used for internal dielectric leakage detection of a motor of a set directly. The performances of the device are superior to those of the original device; and the switching action resistance can be adjusted. The detection device of equipment dielectric leakage can be applied to leakage detection of equipment with different insulating impedance thresholds.
Description
technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a device medium leakage detection device. Background technique [0002] The leak detection device consists of two parts: a detection probe (two electrodes) and a secondary instrument. Among them, the detection probe is a metal part, and the probability of aging and failure is extremely small; the secondary instrument is a modular component composed of electronic components, and the aging failure will gradually increase with time. At present, the detection device has reached the service life (80,000 hours). The country of origin of the equipment has stopped production, and it is difficult to find alternative products that meet the technical parameters and have the same interface in the domestic and foreign markets. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an equipment medium leakage detection de...
