Abstract

The invention discloses a voltage transformer handcart. The voltage transformer handcart comprises a vehicle frame, a rocker-in mechanism, a voltage transformer, a spring, a high-pressure fuse, a plum blossom-shaped contact, a contact arm, a connected insulator, an aviation plug and a bog panel, wherein an observing window is formed in the big panel; the spring and the high-pressure fuse are arranged in the contact arm; the plum blossom-shaped contact is arranged on the end part of the contact arm; the contact arm is connected with the connected insulator. The voltage transformer handcart has the excellent effects that the voltage transformer handcart is suitable for a PT cabinet and a metering cabinet; as an independent drawing unit, the voltage transformer can flexibly go into/out of a power distributing system, and the normal operation of other equipment is not affected; the voltage transformer handcart is very convenient in repairing and low in failure rate and has good interchangeability.

Description

technical field [0001] The invention belongs to the field of high-voltage measurement of electric power systems, and in particular relates to a handcart for voltage transformers. Background technique [0002] Potential transformer is a device for measuring voltage and electric energy in power system or electrical control system. In order to realize the miniaturization of switchgear and facilitate maintenance Affect the overall performance of the metering handcart. Moreover, the installation and maintenance are particularly cumbersome, and there are too many electrical connection parts, and many quality control points have been added, which will bury hidden dangers for the future operation safety of the metering handcart. [0003] As an indispensable measuring device in the power system, the indoor AC high-voltage voltage transformer is mainly used for model collection of measurement and protection control equipment to ensure the normal operation of the power grid system. H...
