مع تطور العلوم والتكنولوجيا واقتصاد السوق, أصبح التحكم الذكي شائعًا بشكل متزايد. متطلبات القدرة الكهربائية, جودة إمدادات الطاقة, وضمان القدرة في الحياة السكنية, إنتاج المؤسسة, الأماكن العامة, الخ. أصبحت أعلى وأعلى. كما أن التيار المقنن لمعدات المحطات الفرعية ومعدات التحكم يتزايد باستمرار; الشبكة الذكية هي اتجاه تطلعي, وذكاء معدات الطاقة هو أساس الشبكة الذكية. معدات المحطات الفرعية, معدات التحكم, ويتم توصيل المعدات الكهربائية بشكل عام من خلال قضيب التوصيل الرئيسي. تعد ذكاء وتوحيد مراقبة درجة الحرارة في نظام إمداد الطاقة بقضيب الأساس لحالة الإرسال في الوقت الفعلي, ظروف درجة الحرارة, وحتى الكشف عن دورية للسلطة. In the practical application of busbar trunking, بسبب التشغيل طويل الأمد في الهواء وتأثير درجة الحرارة والرطوبة المحيطة, التمدد الحراري والانكماش, التحجيم السطحي, قد تحدث الأكسدة أو التآكل, leading to loose contacts and poor contact. Especially in some large buildings (such as large factories, super high-rise buildings, الخ.), where the installation position of busbar trunking cannot be manually monitored, users often neglect the safety management of busbar trunking. Once the temperature of the busbar joints during operation is abnormally overheated, it may lead to fire or major safety and quality accidents, bringing huge and irreparable personal injury and economic and property losses to enterprises.
The bus duct is in a fully enclosed state during operation and is generally in a long-term live state, making daily maintenance and inspection very inconvenient. لذلك, it is necessary to monitor the temperature of the bus joints inside the bus duct to improve the reliability of its operation.

During the operation of power equipment (such as power switchgear), it is often necessary to confirm the operating status of the equipment by measuring the temperature of various parts and components inside the power equipment. Contact temperature measurement is a commonly used method, but in the contact temperature measurement method, it is difficult to install the temperature measuring device on the busbar to ensure the reliable connection between the temperature sensor and the busbar, and to ensure the reliable measurement of temperature. على سبيل المثال, it is fixed with aviation specific adhesive, but the assembly efficiency is relatively low, and the contact stability and reliability are poor.

The busbar refers to the connecting conductors between the main switch in the distribution cabinet and each branch circuit in the power supply system. The busbar may experience temperature rise during operation due to various reasons, but the temperature of the busbar needs to be controlled within a certain range to ensure the normal operation of the power supply system and prevent accidents. لذلك, temperature monitoring of the busbar is necessary at all times.
مع التطور المستمر للتكنولوجيا, various wireless bus temperature measurement devices have been used in the daily maintenance of busbars, which are basically powered by batteries, solar energy, external power supply, self induction power supply, الخ. The device structure is complex.

With the emergence of high-rise buildings and large factories, the electricity consumption in various industries has grown rapidly, and traditional cables can no longer meet the requirements in the transmission of large currents. As a new type of distribution conductor, plug-in bus duct has emerged. Compared with traditional cables, it can fully demonstrate its advantages in high current transmission. لكن, the busbar trunking is exposed to high current and high voltage working environments for a long time. Due to aging, أكسدة, loosening and other reasons, the contact resistance of the busbar contact points and each section of the connection will increase, leading to heating of the busbar, causing safety accidents such as leakage and melting, and even causing fires. لذلك, temperature monitoring of the busbar trunking is particularly important.

حالا, there are several main solutions for temperature monitoring of bus ducts:

1. تكنولوجيا قياس درجة الحرارة بالأشعة تحت الحمراء:

The measurement range is large and the accuracy is high, but with cable communication, cables need to be laid and temperature measurement space is required, making it impossible to achieve integrated integration of busbar equipment and online temperature detection. If there is a fault in the line, it will cause temperature measurement failure on a large area of the line.

2. Wireless temperature measurement technology:

Using wireless communication technology for signal transmission, due to distance limitations, it is necessary to set up adapter nodes (repeaters) at a certain distance to amplify the signal; Wireless signals are greatly affected by obstacles and are prone to attenuation; متى قياس درجة الحرارة لاسلكيا is used, the service life of the power supply battery needs to be considered, and a time-based circuit (أي. supplying power to the system at intervals) is adopted. Although this method extends the service life of the battery, it cannot achieve the function of real-time data collection, which poses a safety hazard.
