Dry-type transformer convenient to disassemble and assemble on telegraph pole, and installation assembly thereof

Abstract

The invention discloses a dry-type transformer convenient to disassemble and assemble on a telegraph pole, and an installation assembly thereof. The dry-type transformer comprises the telegraph pole, a first screw rod, a limiting rod, a hydraulic telescopic rod and a controller, clamping frames are arranged on the outer side of the telegraph pole, a rack is connected between the upper clamping frame and the lower clamping frame, meanwhile, a gear is connected to the outer side of the rack in a meshed mode, and the gear is connected with a transmission shaft; a driving mechanism is arranged in a supporting frame, the upper end of the supporting frame is connected with a fixing frame, the hydraulic telescopic rod is arranged on the fixing frame in a penetrating mode, the inner end of the hydraulic telescopic rod is connected with an abutting frame, and the upper end of the fixing frame makes contact with a first mounting frame. According to the dry-type transformer convenient to disassemble and assemble on the telegraph pole, and the installation assembly thereof, a gear can be driven to rotate under the action of a driving mechanism and a transmission shaft, so that the gear moves on the rack, the height of the fixing frame is adjusted, and the dry-type transformer is convenient to disassemble, assemble, maintain and overhaul; and in addition, the abutting frame can be pushed to abut against the telegraph pole under the action of the hydraulic telescopic rod, so the fixing frame is reinforced and stabilized.

Description

technical field [0001] The invention relates to the related technical field of transformers, in particular to a dry-type transformer which is convenient to be disassembled on a utility pole and an installation assembly thereof. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil. It is widely used in local lighting, high-rise buildings and wharf machinery and equipment. Due to Some dry-type transformers are fixedly installed on utility poles. When the transformer needs to be maintained and repaired, it is troublesome for maintenance workers to climb up and down, and there are certain safety hazards. A dry-type transformer that can be easily disassembled on the utility pole is needed. and its installation components to solve the above problems. Contents of the invention [0003] The purpose of th...
