A pressurized limit alarm and its realization method

Abstract

The invention relates to a pressurization limit alarm and an implementation method thereof. The pressurization limit alarm comprises a transformer body pressing plate, a pressurizing oil cylinder, a ruler unit and an alarm; the transformer body pressing plate is arranged on the top of a transformer body; the pressurizing oil cylinder is mounted between the transformer body pressing plate and an upper clamping component; the moving bracket portion of the ruler unit is mounted on an end portion of the transformer body pressing plate; and the ruler unit is electrically connected with the alarm through an electric wire. According to the method, a bracket and an upper limit adjustment ruler are entirely fixed on the transformer body pressing plate; a reference ruler is mounted at the lower endof a guide rod, and the guide rod and the reference ruler are mounted on the upper clamping component; a distance between the upper limit adjustment ruler and the reference ruler is adjusted to be a predetermined process stroke; and the electrical wire of an magnetic switch on the upper limit adjustment ruler is inserted into the signal input jack of the alarm, after the pressurizing oil pump is started, and the transformer body is compressed in place, the alarm gives out an alarm. With the pressurization limit alarm and the implementation method thereof of the invention adopted, the compacting operation of the transformer body is automatically realized according to the preset process stroke; after the transformer body is compressed in place, the alarm gives out an alarm; and therefore, operation error is reduced, work efficiency is improved, the problem of the excess stroke of the oil cylinder can be solved, and the failure rate of equipment is reduced.

Description

technical field [0001] The invention relates to an alarm, in particular to a pressurized limit alarm and a realization method thereof. Background technique [0002] The compaction process of the transformer body plays a very important role, and it is the main process for controlling the body height and pre-tightening pressure. Preload pressure is an important measure to ensure the strength and rigidity of the body. The pre-tightening force must be achieved so that the coil will not be damaged when encountering an inrush current. [0003] The pressurization process position of the body is pressurized between the body clamp and the coil pressure plate. Because the pressurized space is narrow and the pressure is very high, in order to ensure the overall strength and rigidity of the body, it is necessary to pressurize evenly at multiple places at the same time to form an overall uniform and balanced structure. [0004] The pressure in the body pressurization process is calcul...
