Electric lifting type installation assisting device for current transformer of high-voltage switch cabinet

Abstract

The invention provides an electric lifting type installation assisting device for a current transformer of a high-voltage switch cabinet, and relates to the technical field of current transformer installation. The electric lifting type installation assisting device comprises a transverse pipe, an electric lifting device and a current transformer hook assembly, hooks are arranged at the two ends ofthe transverse pipe respectively, and hanging holes matched with the hooks are formed in the switch cabinet. The current transformer hook assembly comprises a cross beam, a hanging ring is arranged on the upper portion of the cross beam, a lifting hook is arranged on the lower portion of the cross beam, the upper end of the electric lifting device is connected with the cross pipe through a firstconnecting piece, the lower end of the electric lifting device is connected with the hanging ring through a second connecting piece, and the lifting hook is connected with the current transformer. Theinstallation assisting device is simple in structure, low in cost, easy to install and capable of effectively improving the working efficiency and the construction quality, guaranteeing the operationsafety of construction personnel and guaranteeing that the replacement work of the current transformer is completed as expected when the current transformer of the 10kV-35kV high-voltage switch cabinet is replaced and installed.

Description

technical field [0001] The application relates to the technical field of current transformer installation, in particular to an electric lifting installation auxiliary device for a current transformer of a high-voltage switch cabinet. Background technique [0002] With the increasing load demand of power supply users, the transformation ratio capacity of the existing current transformers in the 10kV-35kV high-voltage switchgear in the substation has not met the requirements, so most of the current transformers need to be replaced. Due to the narrow working space of the cable room at the back door of the switchgear and the middle and lower part of the rear of the switchgear is blocked by a partition (current transformer installation base), the operator cannot install the current transformer in a suitable position only by manpower. At present, operators often disassemble the partition (current transformer installation base) as a whole, install the three current transformers on ...

[0002] With the increasing load demand of power supply users, the transformation ratio capacity of the existing current transformers in the 10kV-35kV high-voltage switchgear in the substation has not met the requirements, so most of the current transformers need to be replaced

Due to the narrow working space of the cable room at the back door of the switchgear and the middle and lower part of the rear of the switchgear is blocked by a partition (current transformer installation base), the operator cannot install the current transformer in a suitable position only by manpower

At present, operators often disassemble the partition (current transformer installation base) as a whole, install the three current transformers on the base and then install them as a whole. At this time, the weight of the three current transformers plus the base exceeds 130kg, and Due to the narrow working space, only two people can carry out the installation work. It is difficult to cooperate, and it is easy to cause the current transformer to fall and hurt the workers. The operation risk is high and the work efficiency is low, which often delays the normal power consumption of power supply users and causes complaints from power supply users.
