Embodiment Construction

[0032] The basic principle and structure of the present invention will be described in detail below with reference to the accompanying drawings. The directions of "upper side", "left side" and "right side" in the drawings are described with reference to the direction of the working state of the circuit breaker of the present invention when it is installed on a vertical surface, and are for illustrative purposes only, without any way to limit. The term P pole used in this article refers to the live line, and the N pole refers to the neutral line or neutral line.

[0033] Electronicizing miniature circuit breakers requires the addition of current or voltage transformers to the circuit breaker. However, the miniature circuit breaker has high requirements on the width of the product, which is generally a 9mm modular design, that is, the housing width is usually a multiple of 9mm, so it is a challenge for the miniature circuit breaker.

[0034] The specific structure according to...

Abstract

The invention discloses a modularized electronic miniature circuit breaker, wherein a circuit signal acquiring device, a circuit board assembly and a relay are integrated in a modularized housing, so that the circuit breaker realizes functions of large-current instantaneous tripping, small-current time delay tripping, overload tripping, overvoltage protecting, undervoltage protecting, protection selectivity, multifunctionality, interactive communication, etc. The invention further discloses an electrical system with the electronic miniature circuit breaker for realizing protection selectivity, and a multi-pole modularized electronic miniature circuit breaker.

Description

technical field [0001] The present invention relates to a digital-to-analog electronic miniature circuit breaker, more specifically, to a digital-to-analog electronic miniature circuit breaker used in a terminal power distribution system, and to an electrical system using it and a multi-pole digital-to-analog circuit breaker Electronic miniature circuit breakers. Background technique [0002] The miniature circuit breaker is the most widely used terminal protection device in the electrical terminal power distribution device. The circuit breaker can be connected, carried for a certain period of time and broken current under specified abnormal circuit conditions to provide circuit protection. The current miniature circuit breaker is usually a mechanical type, that is, when the circuit is short-circuited or seriously overloaded, the armature of the over-current release is attracted, so that the free trip mechanism operates, and the main contact disconnects the main circuit. W...
