disconnector is a kind of electrical equipment, mainly used to isolate different parts of the circuit in order to protect the safety of personnel when repairing, overhauling or replacing electrical equipment. The functions and roles of isolators are very important, and the following details the classification of isolators.

Classification of disconnector

disconnector are commonly used in industrial automation, power systems and communication networks to ensure isolation and protection between signals or circuits. Isolators can be divided into several categories, including mechanical isolators, capacitive isolators, optical isolators and transformer isolators, etc.

Mechanical disconnector:It is the most basic isolator, which usually consists of a pair of mechanical contacts. When a circuit passes through the isolator, the mechanical contact will open so that the signal cannot pass through. The advantage of this isolator is simple and economical, but the service life is short.

Capacitive disconnector:A capacitor is used to isolate a circuit, usually when transmitting low frequency signals. This type of isolator has better isolation and transmission performance, but for high frequency signals, the capacitive isolator becomes less effective.

Opto disconnector:Isolates circuits by optical signals, usually consisting of optical fibers or light emitting diodes (LEDs) and photodiodes (PDs). Optical isolators have high isolation effect and better transmission performance, and are widely used in industrial automation, communication networks and other fields.

Transformer disconnector :Use transformer to isolate the circuit and isolate the signal by mutual inductance. This kind of isolator has the best isolation effect and is suitable for high frequency signals. It is widely used in power systems and industrial automation and other fields.
