Description

Technical Field

[0001] This utility model relates to a temperature and voltage acquisition device, and more particularly to a temperature and voltage acquisition device applicable to various miniature circuit breakers. Background Technology

[0002] Miniature circuit breakers (MCBs) are the most widely used terminal protection devices in building electrical distribution systems. Current technologies for temperature and voltage acquisition from miniature circuit breakers mainly include the following two methods:

[0003] One method involves collecting data by connecting the outgoing lines of the circuit breaker to the parallel lines. However, when there are many parallel lines with defects, there may be cases of false connections. Furthermore, the operation is complex and prone to repeated checks.

[0004] Another method involves collecting data from the top of the miniature circuit breaker, specifically at the screw of the locking mechanism. However, this method is not compatible with most brands of circuit breakers. Since their depth, aperture, and appearance are not the same, various specifications and sizes of accessories are required to complete the process. The wide variety of types of accessories and matching present significant challenges in terms of cost and compatibility.

[0005] A search revealed that Chinese Patent Publication No. CN118168674A discloses a temperature and voltage acquisition device for an air switch. This device is mounted on the terminals of the air switch and includes a snap-fit ​​plastic shell, a rubber-coated wire harness body, a three-core rubber-coated wire harness, a voltage acquisition module, a temperature acquisition module, copper components, a contact spring, and a temperature probe. This existing patent's temperature and voltage acquisition device can only acquire data from devices with large apertures. Furthermore, direct installation suffers from issues such as unreliable contact, inconvenient installation, and poor safety. Utility Model Content
