Abstract
The utility model relates to a method of great current impact test for flat-conductor welding samples and a special device thereof, which belongs to the field of auxiliary equipments for transformer manufacture. The technical scheme of the utility model is that the above special device consists of a main body and a tensioning system. The main body comprises a fixed plate (1), a base plate (2) and a baffle plate (3), which are welded together. The fixed plate and the baffle plate are arranged at both sides of the base plate respectively. The fixed plate is equipped with block holes and the baffle plate is equipped with through holes. The tensioning system comprises springs (4), screws (5) and nuts (6). The screws match with the nuts. The screws traverse the through holes of the baffle plate. Notches are arranged at the head of the screws. Springs are arranged between the screws and the nuts. The special device of the present utility model is used in cooperation with conventional current output devices to test flat-conductor welding samples. The above device of the utility model has the advantages that the quality of welding points can be determined by checking the mechanical force and high temperature environment withstood by conductors under the simulation condition of short-circuit transformers during the process of quality check of welding points, thereby increasing the operating efficiency and product quality.
Description
Affiliated technical field:
The utility model relates to a kind of strip conductor welding exemplar great current impact test isolated plant, belongs to transformer and makes the utility appliance technical field.
Background technology:
Strip conductor is widespread use in power transformer, and the welding operation of lead in use is absolutely necessary.Lead forms circuit loop in transformer, if there are quality problems in the wire bonds point, transformer can not be worked, so the quality check of pad is extremely important.Owing to there is not practical field quality check device, be difficult to guarantee the power transformer product quality, people are badly in need of a kind of device that is applied to the pad quality check, and during the analogue transformer short circuit, lead bears mechanical force and hot environment, to judge the pad quality of lead.
The utility model content:
The utility model purpose provides a kind of strip conductor welding exemplar great current impact test isolated plant, during the analogue transformer short circuit, lead bears mechanical force and hot environment, to judge the pad quality of lead, increase work efficiency and product quality, solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: strip conductor welding exemplar great current impact test isolated plant, comprise main body, tension system two parts, main body is made of fixed head, base plate, plate washer welding, fixed head, baffle plate are separately positioned on the two ends of base plate, are provided with hole clipping above the fixed head, are provided with through hole above the baffle plate; Tension system is made up of spring, screw rod, nut, screw rod and nut coupling, and screw rod passes the through hole on the baffle plate, and the head of screw rod is provided with draw-in groove, is provided with spring between screw rod and the nut.
