Transformer anti-theft device

Abstract

The invention belongs to the field of transformers, and relates to a transformer anti-theft device. The transformer anti-theft device comprises a fixing rod, the outer surface of the fixing rod is fixedly connected with a lateral clamping mechanism, rubber plates are arranged on the two sides of the lateral clamping mechanism, the outer surfaces of the rubber plates are fixedly connected with the two ends of the fixing rod. According to the transformer anti-theft device, a hydraulic mechanism is arranged, after a transformer is installed on the upper surface of the fixing rod, the hydraulic mechanism moves downwards along with the transformer, a pressing plate clamps the upper surface of the transformer, after a lantern ring moves to a designated position, a hydraulic pipe pumps hydraulic oil into a hydraulic cylinder, a U-shaped pipe retracts into the hydraulic cylinder under the influence of oil pressure, a limiting rod abuts against the outer surface of a telegraph pole towards the interior of the lantern ring, under the action of counter-acting force, the inner surface of the lantern ring makes closer contact with the outer surface of the telegraph pole, a gap between the lantern ring and the telegraph pole is eliminated, friction force is increased, and the problem that a gap is likely to be generated due to size mismatch because too large diameter of the lantern ring can be solved.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to a transformer anti-theft device. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). [0003] Since the inner coil of the transforme...
