10kv current transformer replacement operation trolley

Abstract

A 10kV current transformer replacement trolley, which includes a trolley mobile platform on which a folding lifting frame is fixedly arranged, and a rack and pinion moving mechanism is arranged on the folding lifting frame, and the front ends of the rack and pinion moving mechanism are connected to each other. An L-shaped supporting plate with a fixed current transformer is connected; the base of the mobile platform of the trolley is equipped with four moving wheels; the middle of the folding lifting frame installed on the mobile platform of the trolley is provided with a rack adjustment mechanism for height adjustment, and the trolley moves One side of the platform is also provided with handrails; the folding lifting frame is fixed as one with the rack and pinion moving mechanism through a connecting iron piece; the rack of the rack and pinion moving mechanism is a telescopic rod or is specially connected with a The rods are connected into one body, and one end of the telescopic rod is welded and fixed with an integrated right-angled L-shaped support plate; it has the characteristics of ensuring the installation level of the current transformer, saving time and effort, and high work efficiency.

Description

technical field [0001] The invention relates to a 10kV current transformer replacement operation trolley, in particular, it belongs to a tool used for operation in a 10kV switch cabinet. Background technique [0002] Power grid enterprises often need to replace the current transformers in the outgoing line interval due to the change of outgoing line load, most of which are 10kV transformers. When replacing, hold the transformer with manpower, remove and install the fixing screws. The problem is: each transformer weighs 10 to 20 kilograms, and the installation space is extremely narrow, the height is between 40 cm and 100 cm, and the lateral movement space of personnel is less than 80 cm. If the force is too low, improper force or insufficient force will also cause injuries to personnel and damage to equipment. In addition, the replacement of current transformers is often carried out in conjunction with other power outages. Under the current situation of shortage of operato...

Problems solved by technology

The problem is: each transformer weighs 10 to 20 kilograms, and the installation space is extremely narrow, the height is between 40 cm and 100 cm, and the lateral movement space of personnel is less than 80 cm. Low, improper force or insufficient force will also cause personnel injuries and equipment damage

In addition, the replacement of current transformers is often carried out in conjunction with other power outages. Under the current situation of shortage of operators, the work progress is often affected and the power transmission time is delayed.
