A transformer anti-theft device

Abstract

The invention belongs to the field of transformers, and is specifically an anti-theft device for transformers, including a fixed rod; the outer surface of the fixed rod is fixedly connected with a lateral clamping mechanism, and rubber plates are arranged on both sides of the lateral clamping mechanism , the outer surface of the rubber plate is fixedly connected to both ends of the fixing rod. The transformer anti-theft device is equipped with a hydraulic mechanism. When the transformer is installed on the upper surface of the fixed rod, the hydraulic mechanism moves downward. The pressure plate clamps the upper surface of the transformer. The hydraulic oil is drawn out from the inside of the hydraulic cylinder. Affected by the oil pressure, the U-shaped tube is retracted into the hydraulic cylinder, and the limit rod is pushed against the outer surface of the utility pole to the inside of the collar. Under the action of the reaction force, the inner surface of the collar and the wire The outer surface of the pole is in closer contact, the gap between the collar and the pole is eliminated, the friction is increased, and the problem that the collar is too large and the size does not match, and the gap is easily generated is 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...
