随着电表的发展,继电器也迅速发展,已成为电表中不可或缺的重要组成部分。它们具有体积小、负载能力强、输入与输出之间高隔离、低功耗和低温升的特点。它们在市场上占有较高的份额,广泛应用,受到消费者的青睐。继电器最初主要用于IC卡预付费电表和集中抄表系统。近年来,继电器在无功补偿设备的复合开关中得到了广泛应用。当与晶闸管在复合开关中一起使用时,它们已成为无功补偿设备中的主要开关设备,用于切换大电流电路。它们还可以应用于各种家用电器和自动控制设备(如照明控制系统)。
Relays ka faidaan da jaiza
- It features high reliability. Due to the strict selection of military-grade components, the reliability of the relay has been significantly enhanced. All electrical connection points are connected with fasteners. The relay's working power supply adopts an independent power supply mode. All output signals of the relay are isolated and transformed without interfering with each other. The cables used for connection with various instruments and meters are double-shielded cables. As long as one end is reliably grounded, the interference introduced by the line can be effectively suppressed.
- Relays can protect motors under various starting conditions and have high operational reliability, such as motor overload and phase loss protection, as well as grounding protection. They can be centrally controlled by a computer, enhancing the degree of automation in the power distribution system and bringing the dispatching and maintenance of the power distribution and control systems to a new level.
- The relays produced are based on the total current law and adopt the two-stage automatic temperature compensation technology and the most optimized circuit structure design technology. In the magnetic circuit, the latest materials and process technologies are selected in accordance with the principles of center and axis symmetry, ensuring the theoretical calculation accuracy requirements of the product in practical applications. A three-stage differential amplifier circuit is adopted to eliminate the error caused by the output resistance of the Hall element being greater than the input internal resistance of the operational amplifier, ensuring that the sampling values are reflected without distortion and meeting the design requirements.
- Die produzierten Relais basieren auf dem Prinzip der Symmetrie. Die Luftspalte innerhalb des geschlossenen magnetischen Kreislaufs sind gleichmäßig in geraden Vielfachen verteilt. Die technischen Parameter des Hall-Elements sind streng abgestimmt. Ein einzigartiger Schaltkreis zur Entfernung von Restmagnetismus wird verwendet, um die Widerstandsfähigkeit des Produkts gegen externe magnetische Störungen zu erhöhen. Eine zweistufige automatische Temperaturkompensationstechnologie wird eingesetzt, um sicherzustellen, dass das Produkt sich aufgrund des Einflusses der externen Umwelttemperatur nicht in der Abweichung ändert. Die Annahme von vollständig geschlossenen Anti-Korrosions- und staubdichten Maßnahmen, jedoch ohne das Hall-Element im Luftspalt abzudichten, dient dazu, die Situation zu verhindern, in der ein einzelnes Hall-Element beschädigt wird und nicht ersetzt werden kann. Selbst wenn ein falscher Wert künstlich im Schaltkreis angepasst wird, geht das Symmetrieprinzip vollständig verloren, wodurch die Garantie für die Auswirkungen des Exzentrizitätsfehlers nicht gegeben ist.
Ngokwe mvelaphi yokulungiswa kwesakhiwo sezimboni, ukunciphisa ukusetshenziswa kwamandla ku-gross domestic product kanye nokufeza ukuthuthukiswa komnotho okuphansi kwekhabhoni, isizukulwane esisha semikhiqizo ye-relay esindisa amandla, esindisa izinto futhi enezinga eliphezulu lokusebenza sizothokozela ukuthuthukiswa okukhulu. Ukudinga kwemakethe kuyakhula, okukhombisa ithuba eliyingqayizivele lokuguqulwa nokuthuthukiswa komkhakha wezinsiza zikagesi eziphansi.
Ukusebenzisa ithuba lokukhula okusheshayo kwamandla amasha emakethe, imboni ye-relay ihlaziye kahle isimo futhi yanda ukuguqulwa kwayo kokwakha nokuqinisa, ihlinzeka ngethuba elihle lokwandiswa nokuthuthukiswa kwemboni. Iphumelele ukwandisa imikhiqizo yayo ezindaweni ezifana nezinguquko zamandla ezitholakala ku-photovoltaic, izinhlelo zokulawula nokuvikela amandla amasha, amandla ahlukanisiwe, imishini yokugcina amandla, kanye nemishini ye-DC switchgear.
Relays zizokuba yindlela yokucwaninga nokuthuthukisa ye-relays. I-relays yokuxhumana isibe yisikhala esikhulu sokusebenza, futhi i-relays yesithathu isetshenziswa kabanzi. I-relays ye-solid-state isebenzisa ubuchwepheshe be-microelectronics. Imikhiqizo ithuthuka ngendlela yokuhlakanipha nokuhlanganiswa, futhi isidingo semakethe sikhula kancane kancane. Njengomakethe yesibili enkulu yokusebenza kwe-relay, umkhakha wezimoto ubona ukwanda okuqhubekayo kokusetshenziswa kwezimoto ngakunye kanye nokwandiswa okusheshayo kwezinhlobo zemikhiqizo.
