Problems solved by technology
[0003] Due to the relatively compact space in the switchgear, small lifting equipment cannot enter. Therefore, the main method of replacing the handcart switchgear CT in the substation is to use manpower for handling and loading and unloading. This requires a large number of people to participate in the replacement, which wastes human resources. There are also great risks and hidden dangers to personal and equipment safety through manual handling and loading and unloading, and the construction progress is relatively slow when manually dismantled and replaced, and for safety reasons during construction, it is required to shorten the power outage time as much as possible. Therefore, there is a need for some easy-to-use support aids to shorten CT handling and installation time, while improving safety

The invention discloses an auxiliary trolley for installation and transportation of a 10kV switch cabinet CT. The auxiliary trolley comprises a transportation trolley body, a grabbing module, a lifting module and a control module. The lifting module, the grabbing module and the control module are integrated on the transportation trolley; and the grabbing module is arranged above the lifting module. The lifting module comprises a supporting frame, a lifting plate I, a lifting plate II, a lead screw I, a lead screw II and a lead screw III. The support frame is fixed on the transportation trolley, and a lifting plate I is arranged above the support frame; a lifting plate II is arranged above the lifting plate I, a lead screw II and a lead screw III are fixed on the lifting plate II, and a motor is connected above the lead screw II and the lead screw III; a screw rod I is fixed on the lifting plate I; the grabbing module comprises a supporting lever and a mechanical arm. The control module comprises a PLC, and the PLC controls the motor to work. The working environment of CT installation is met, CT installation can be completed without multi-person operation, the maintenance work requirement is met, and the purpose of rapidly and safely completing CT installation and transportation is achieved.
Description
technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an auxiliary trolley for CT installation and transportation of 10kV switch cabinets. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, current transformers (CT) and various protection devices. Among them, the current transformer (CT) is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. [0003] Due to the relatively compact space in the switchgear, small lifting equipment cannot enter. Therefore, the main method of replacing the handca...
