High-voltage switch integrated metering device

Abstract

The invention discloses a high-voltage switch integrated metering device. The high-voltage switch integrated metering device comprises a control box and three phases of supporting columns fixed to thecontrol box, wherein an upper wiring conducting rod connected with a vacuum arc extinguishing chamber static conducting rod is arranged on the upper portion of each phase of supporting column; each upper wiring conducting rod is fixedly sleeved with a capacitor of a hollow structure; the capacitors comprise the voltage signal collecting capacitor and the power capacitor; each phase of supportingcolumn is provided with an arc-shaped side wall protruding towards the outer side of the side wall; two axial line holes penetrating through the side wall are formed in each protruding arc-shaped sidewall; and a circuit board is fixed to the bottom in the control box. According to the high-voltage switch integrated metering device, a traditional voltage transformer is abandoned, voltage signals are collected through electronic components, current signals are collected through a primary core-penetrating nanocrystalline magnetic ring current transformer, calculation of electric energy values and other related data is conducted through an ultra-low power consumption single chip microcomputer circuit, connecting nodes are reduced, the failure rate is reduced, and the high-voltage switch integrated metering device is small in size, low in weight and convenient to transport and install.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution, and in particular relates to a high-voltage switch integrated metering device. Background technique [0002] At present, the high-voltage switch integrated metering device on the market needs to use three independent components: a high-voltage switch, a high-voltage voltage, a current transformer, and a high-voltage meter. Also, voltage and current transformers are needed to obtain the corresponding calculation and acquisition signals. Therefore, this combination of discrete components not only takes up a lot of space, but also requires troublesome installation and cumbersome wiring, and increases the failure rate at the same time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a brand-new high-voltage switch integrated metering device. [0004] In order to solve the problems referred to above, the technical sc...
