Embodiment

[0020] Example: such as Figure 1-3 As shown, a 20kV switch transfer device includes a manual hydraulic operating system 4, a chassis 2 and a door frame 1, and a pair of front wheels 31 and a pair of rear wheels 32 are arranged on the chassis 2, wherein the front wheels 31 are linear wheels, and the rear wheels 32 It is a universal wheel with brakes, which is convenient for the flexible movement of the device. A pair of vertically movable brackets 5 that can be controlled by a manual hydraulic operating system 4 are arranged on the left and right sides of the door frame 1, and the distance between the brackets 5 can be adjusted. Wherein the height of the mast 1 is 2100mm, the lifting height is 1600mm, the width of the chassis 2 is 1200mm, and the maximum lifting weight is 500kg. Both the chassis 2 and the mast 1 are made of high-strength C-shaped steel to ensure no deformation under load.

Abstract

The invention relates to a 20kV switch transfer device. The 20kV switch transfer device comprises a manual hydraulic operation system, a base plate and a portal, a pair of front wheels and a pair of rear wheels are arranged on the base plate, and a pair of brackets which can be controlled to perpendicularly move by the manual hydraulic operation system is arranged on the left and on the right of the portal. The 20kV switch transfer device has the advantages that only one to two 20kV switch transfer devices configured on each transformer substation can meet switching operation needs of the whole substation, configuring quantity of the 20kV switch transfer devices is controlled, and accordingly the problem of field insufficiency is solved; the 20kV switch transfer device has an automatic unloading function, a switch handcart pulled out of a switch cabinet can be disposed in an overhaul field quite conveniently, and the requirements of standardization are met; rails of the 20kV switch transfer device can be adjusted according to switch models, and accordingly chaotic use of 20kV switch transfer devices due to different models is avoided; and unloading speed of carrying trolleys conforms to working habits of users, and multi-functionality is achieved.

Description

technical field [0001] The invention relates to an auxiliary tool for a power system, in particular to a 20kV switch transfer device. Background technique [0002] With the continuous advancement of 20kV transformation, the commissioning and maintenance of 20kV lines in substations has increased, making the operation of substations more frequent, resulting in the following problems: [0003] 1. The configuration quantity of the switch transfer device. Since there are many 20kV outlet switches during operation, it is necessary to use a switch transfer device during the switching operation. When multiple outlet switches are switched at the same time, it is necessary to invest in multiple switch transfer devices. According to the current configuration of switch transfer devices in substations, it is necessary to purchase a large number of switch transfer devices to meet normal use, which requires a lot of money. Expenses, and when there are few operating tasks, a large number...
