A transformer loose reminder device

Abstract

The invention relates to the technical field of transformers, and discloses a transformer loosening warning device, which includes a winding, an upper iron yoke is fixedly connected to the inside of the winding, and first positioning blocks are fixedly connected to both sides of the upper iron yoke. The side of the block away from the upper iron yoke is fixedly connected with the first pin, the upper part of the upper iron yoke is fixedly connected with the upper fixed block, the inside of the upper fixed block is fixedly connected with a pole, and the side of the pole away from the upper fixed block is fixedly connected with a The lower fixed block is fixedly connected with the lower iron yoke above the lower fixed block; the transformer loosening reminder device touches and squeezes the peripheral contact plate through the coil, and the contact plate approaches the two adjacent pressure plates and squeezes For the sponge on the outside, the outer wall of the contact plate touches the two adjacent pressure plates, causing the circuit to be connected, and the current flows from one pressure plate to the contact plate and then to the other pressure plate, forming a complete circuit, thus triggering the buzzer. The flute device achieves the effect of reminding.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer loosening warning device. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage to boost or step down the power, which is convenient for the transportation and use of power. The transformer is often impacted by the short-circuit current during operation. Due to the limited bearing capacity of the transformer and the There is a possibility of failure of the protection system, which will cause the winding to loosen. The transformer may be impacted during transportation and installation, which will also cause the winding to shift, which will further lead to deformation or even scrapping of the winding, destroying the transformer, and increasing construction costs. It can affect the work progress and reduce the work efficiency. It can be seen that it is necessary to remind the loose w...

[0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage to boost or step down the power, which is convenient for the transportation and use of power. The transformer is often impacted by the short-circuit current during operation. Due to the limited bearing capacity of the transformer and the There is a possibility of failure of the protection system, which will cause the winding to loosen. The transformer may be impacted during transportation and installation, which will also cause the winding to shift, which will further lead to deformation or even scrapping of the winding, destroying the transformer, and increasing construction costs. It can affect the work progress and reduce the work efficiency. It can be seen that it is necessary to remind the loose winding of the transformer. However, this situation is very sudden. The existing detection equipment is inconvenient for real-time detection of the winding. Remind the staff to make adjustments before further deterioration, which brings great inconvenience to the construction

[0003] Aiming at the deficiencies in the prior art, the present invention provides a transformer loosening warning device, which has the advantage of reminding and warning when the winding is loose, and solves the problem that the state of the winding cannot be observed in real time, so that the circuit is connected when the winding is loose, and the current is controlled by a pressurized transformer. The plate flows to the contact plate and then to another pressure plate to form a complete circuit, thus triggering the whistle device to achieve the effect of reminder
