The invention relates to the field of a ring main unit and discloses a mechanical life experiment device of a toggle switch of the ring main unit. The device comprises a test bench, two air cylindersand pushing parts, wherein an upper end surface of the test bench is provided with a test groove for placing the toggle switch, the two air cylinders are located on two symmetrical sides of the test groove and fixed to an upper end face of the test bench, the pushing parts correspond to the air cylinders, are fixed on the upper end surface of the test bench, and are in power connection with outputshafts of the corresponding air cylinders, when the toggle switch is tested, the toggle switch is placed in the test groove, the toggle direction of the toggle switch is consistent with the pushing direction of the pushing parts, the air cylinders are started, the output shaft of one air cylinder is made to extend out, the toggle switch is pushed, when a toggle rod of the toggle switch is toggledonce, the output shaft of the other air cylinder just extends out. The device is advantaged in that the pushing parts toggle the toggle rod of the toggle switch back and forth through the movement process of the air cylinders, so automation of the mechanical life test of the toggle switch is realized, and labor cost and time cost are saved.
Description
technical field [0001] The invention relates to the field of ring network cabinets, in particular to a mechanical life experiment device for a toggle switch of the ring network cabinet. Background technique [0002] Ring Main Unit (Ring Main Unit) is a set of high-voltage switchgear installed in metal or non-metal insulated cabinets or electrical equipment made into assembled interval ring network power supply units. The core part uses load switches and fuses, which has a simple structure. , small size, low price, can improve power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. Some switches used in ring network cabinets, such as toggle switches, generally require their electrical and mechanical properties to remain stable within the specified number of toggles. Therefor...
