Product descriptions from the supplier

Description

Overview

DDHV V type center break disconnector is a compact, reliable and easy-to operate substation equipment.

Suitable for applications up to 145 kV voltage level, DDHV is designed for installation in outdoor switchyards. It has two moving insulators per phase arranged in a ‘V’ configuration, which makes DDHV design compact and simple.  Due to this, DDHV is a preferred solution for substations where space is costly or limited.

DDHV disconnectors enable flexible design and reliable operations. Built-on earth switches are available and can be mounted on one or both sides of the disconnector.

Applications

  • Substations in small areas

  • Pole-top mounted

  • Mobile substations

    Installation Requirements and Procedures for 10 kV High-Voltage Disconnect Switches
    First, the installation of 10 kV high-voltage disconnect switches must meet the following requirements. The first step is to select an appropriate installation location, typically near the switchgear power supply in the power system to facilitate operation and maintenance. At the same time, sufficient space must be ensured at the installation site to accommodate equipment placement and wiring.Secondly, equipment safety must be fully considered—for example, lightning protection and explosion-proo

    Common Issues and Handling Measures for 145kV Disconnector Control Circuits
    The 145 kV disconnector is a critical switching device in substation electrical systems. It is used in conjunction with high-voltage circuit breakers and plays an important role in power grid operation:First, it isolates the power source, separating equipment under maintenance from the power system to ensure personnel and equipment safety;Second, it enables switching operations to change the system operating mode;Third, it is used to interrupt small-current circuits and bypass (loop) currents.Re

    What are the six operating principles of disconnect switches?
    1. Operating Principle of the DisconnectorThe operating mechanism of the disconnector is connected to the active pole of the disconnector via a connecting tube. When the main shaft of the mechanism rotates 90°, it drives the insulating pillar of the active pole to rotate 90°. The bevel gears inside the base drive the insulating pillar on the other side to rotate in the opposite direction, thereby achieving opening and closing operations. The active pole, through inter-pole linkage tubes, drives

    36kV Disconnect Switch Selection Guide & Key Parameters
    Selection Guidelines for 36 kV Disconnect SwitchesWhen selecting the rated voltage, ensure that the disconnect switch’s rated voltage is equal to or higher than the nominal voltage of the power system at the installation point. For example, in a typical 36 kV power network, the disconnect switch must have a rated voltage of at least 36 kV.For rated current, selection should be based on the actual long-term load current. Generally, the switch’s rated current must be no less than the maximum conti

    Copper Conductor Size vs Temperature Rise in 145kV Disconnectors
    The relationship between the temperature-rise current of a 145 kV disconnector and copper conductor size lies in balancing current-carrying capacity and heat dissipation efficiency. The temperature-rise current refers to the maximum continuous current a conductor can carry without exceeding its specified temperature rise limit, and the copper conductor size directly influences this parameter.Understanding this relationship begins with the physical properties of the conductor material.
