Heavy-current impact test method of laminar-conductor welding sample and special device thereof

Abstract

The invention relates to a heavy-current impact test method of a laminar-conductor welding sample and a specific device thereof, belonging to the technical field of a transformer manufacture auxiliary device. The specific device comprises a main body and a tension system, wherein the main body is formed by welding a fixing plate (1), a bottom plate (2) and a baffle plate (3); the fixing plate and the baffle plate are respectively arranged at both ends of the bottom plate, a clamping hole is arranged on the fixing plate, and a through hole is arranged on the baffle plate; the tension system comprises a spring (4), a screw rod (5) and a nut (6), wherein the screw rod is matched with the nut and passes through the through hole of the baffle plate, the head of the screw rod is provided with a clamping groove, and the spring is arranged between the screw rod and the nut. The specific device is matched with the common current output device to test the laminar-conductor welding sample. The invention can be used for checking the quality of welding points and simulating mechanical force born by conductors and high-temperature environment in order to judge the quality of the welding points of the conductors and increase work efficiency and product quality.

Description

[0001] Technical field: [0002] The invention relates to a high-current impact test method and a special device for a flat wire welding sample, and belongs to the technical field of transformer manufacturing auxiliary equipment. Background technique: [0003] Flat wires are widely used in power transformers, and the welding operation of the wires is essential during use. The wire forms a circuit loop in the transformer. If there is a quality problem in the welding point of the wire, the transformer will not work, so the quality inspection of the welding point is very important. Since there is no practical on-site quality inspection device, it is difficult to guarantee the quality of transformer products. People urgently need a device for welding joint quality inspection. When the transformer is short-circuited, the wire is subjected to mechanical force and high temperature environment to judge the welding point quality of the wire.
