Transformer looseness reminding device

Abstract

The invention relates to the technical field of transformers. The invention further discloses a transformer looseness reminding device. The reminding device includes a winding, the inside of the winding is fixedly connected with an upper iron yoke; two sides of the upper iron yoke are fixedly connected with first positioning blocks; first pins are fixedly connected to the sides, away from the upper iron yoke, of the first positioning blocks, an upper fixing block is fixedly connected to the upper portion of the upper iron yoke, a supporting rod is fixedly connected into the upper fixing block,a lower fixing block is fixedly connected to the side, away from the upper fixing block, of the supporting rod, and a lower iron yoke is fixedly connected to the upper portion of the lower fixing block. According to the transformer looseness reminding device, the coil touches and extrudes the peripheral contact plate; the contact plate is close to the two adjacent pressed plates and extrudes thesponge on the outer side, the outer wall of the contact plate touches the two adjacent pressed plates to conduct a circuit, current flows from one pressed plate to the contact plate and then flows tothe other pressed plate, a complete circuit is formed, and therefore the whistling device is triggered, and the reminding effect is achieved.

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
