Trolley conductor insulator

Abstract

The invention relates to a trolley conductor insulator and belongs to the technical field of electric power supply and distribution. The upper and lower ends of a porcelain insulator of the trolley conductor insulator are connected with internal thread bosses of upper and lower bottom plates. The upper and lower bottom plates are inserted in grooves of upper and lower seats respectively to form a moving pair. The upper and lower seats are fixed on the lower surface of a trolley conductor and the upper surface of a support frame respectively. A lock lever is hinged to one side of at least one of the grooves of the upper and lower seats, one end of each lock lever is provided with a contact surface, the other end of the lock lever is provided with a lock tending to approach the corresponding bottom plate, and one side of the bottom plate, corresponding to the lock, is provided with lock teeth. When the bottom plates are inserted into the grooves, the contact surfaces of the lock levers leave from each other, the locker levers shift, and the locks leave the bottom plates. When the bottom plates are inserted into the grooves and leave the contact surfaces of the lock levers, the lock levers reset, and the locks contact with the bottom plates and fasten into the lock teeth. Through adoption of the trolley conductor insulator, the porcelain insulator can be demounted and mounted once conveniently.

Description

technical field [0001] The invention relates to an insulator, in particular to a trolley line insulator, and belongs to the technical field of electric power supply and distribution. Background technique [0002] According to the applicant's knowledge, trolley lines (also known as grinding rails or friction rails) are widely used in metallurgical and chemical enterprises to supply power for large-scale mobile electromechanical equipment of enterprises. However, due to the serious pollution of heavy industrial enterprises and the heavy workload of equipment, the trolley line of the existing structure is relatively easy to be damaged. Among them, the trolley line insulator is made of ceramic material, which is often affected by factors such as temperature difference, corrosion, and external force, which often cause cracks in the porcelain bottle body, resulting in insulation failure and need to be replaced frequently. However, the trolley line insulator assembly relies on scr...

However, due to the serious pollution of heavy industrial enterprises and the heavy workload of equipment, the trolley line of the existing structure is relatively easy to be damaged

Among them, the trolley line insulator is made of ceramic material, which is often affected by factors such as temperature difference, corrosion, and external force, which often cause cracks in the porcelain bottle body, resulting in insulation failure and need to be replaced frequently

However, the trolley line insulator assembly relies on screws to fasten the two ends of the insulating porcelain bottle, which makes it extremely inconvenient to replace the insulator, and due to the poor working environment, the screws are often severely corroded, and as a result, acetylene cutters have to be used for replacement

In addition, the judgment of insulator failure often depends on the naked eye observation of equipment maintenance personnel, and there is no ideal device to detect whether the insulation performance of insulating components is intact
