Abstract

The utility model relates to transformer safety detection equipment, in particular to a transformer core detection device which consists of a temperature probe, a data line, a temperature digital display and a wireless alarm generator. The transformer core detection device is characterized in that the temperature probe is arranged in a transformer core, the temperature probe is connected with the temperature digital display through the data line, and the temperature digital display is connected with the wireless alarm generator. The transformer core detection device has the positive effects of high economy, high efficiency and high accuracy.

Description

The transformer core pick-up unit
Technical field
The utility model relates to the transformer security detection equipment, is specially the transformer core pick-up unit.
Background technology
After the elementary winding energising of transformer, the magnetic flux that coil produced flows at iron core, because iron core itself also is a conductor, will induced potential on perpendicular to the plane of the magnetic line of force, and this electromotive force forms the closed-loop path and produces electric current on the section of iron core.This " eddy current " increases the loss of transformer, and makes the iron core heating of transformer, and the temperature of transformer increases.We are called " iron loss " loss that is produced by " eddy current ".Can cause serious safety after the temperature of transformer reaches necessarily is accident.
Summary of the invention
The utility model is just at above technical matters, provide a kind of economy, efficiently, transformer core pick-up unit accurately.
Concrete technical scheme of the present utility model is:
The transformer core pick-up unit, it is made up of temp probe, data line, temperature device for digit-displaying, radio alarming generator, it is characterized in that: temp probe is arranged on the transformer fe in-core, and temp probe connects the temperature device for digit-displaying by data line, and the temperature device for digit-displaying connects the radio alarming generator.
" eddy current " increases the loss of transformer, and make the iron core heating of transformer, temp probe passes to the temperature device for digit-displaying with the temperature data of measuring, and notifies the situation of transformer at once by the alert generator of report from a liner, according to the temperature of transformer in advance property handle the accident that prevents and take place.
Good effect of the present utility model shows: economical, efficient, accurate.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, 1---temp probe, 2---data line, 3---temperature device for digit-displaying, 4---radio alarming generator.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Specific embodiment:
The transformer core pick-up unit, it is made up of temp probe, data line, temperature device for digit-displaying, radio alarming generator, temp probe is arranged on the transformer fe in-core, and temp probe connects the temperature device for digit-displaying by data line, and the temperature device for digit-displaying connects the radio alarming generator.
" eddy current " increases the loss of transformer, and make the iron core heating of transformer, temp probe passes to the temperature device for digit-displaying with the temperature data of measuring, and notifies the situation of transformer at once by the alert generator of report from a liner, according to the temperature of transformer in advance property handle the accident that prevents and take place.
