Bayani na sayen daga mai wuyaci

Sharararwa

Siriya DNH40 (a sani da za a tattauna "siriya") yana daidaita wa a tattalin arziki na karkashin abincin 50Hz/60Hz da ingancin karamin kofin 1000V. Ana gina shi don ya baka da ya kusa hanyar tattalin arzikin kafin kusa, da kuma zama mai mahimmanci a cikin karkashin gwamnati, kasa, tsirrai, kimiyar lada, da kuma gwamnatin automatika.

Mutane na Siriya

1、Modular Design

Siriya DNH40 ta da kayan aiki mai modula wanda ake iya gudanar da ita a cikin yanayin mawakin masu bukatar.

2、Durable Construction

Kayan aiki na siriya ta samun resin na polyester na unsaturated da ake kashe da fiber na glass, wanda ya ba shi nasarorin dole, karamin kofin, kuma alaƙarwa ga karamin kofin da kuma alaƙarwa ga karshen ƙarami.

3、Efficient Operating Mechanism

An fito shi da mekanisim na double spring energy storage, wanda ya ba shi nasarorin dole don koyar da spring a lokacin da ake yi aiki, wanda ya ba shi nasarorin koyar da shiga da kusa. Wannan mekanisim ba ne da muhimmanci game da rike ƙaramin kofin, amma ya saukar da kyakkyawan aiki.

4、Rotary Contact Structure

Kayan aiki na rotary multi-breakpoint contact structure ya ba shi nasarorin dole don koyar da safe isolation distance, wanda ya daidaita waɗannan mutanen da suka fi sani.

5、Visual Indicator

Yanayin moving contact yana da nasarorin dole don koyar da visibility through a window, wanda ya ba shi nasarorin dole don koyar da safe operation.

6、Clear Status Indication

Siriya ta da ON/OFF indicator. A lokacin da shi yake a “O” position, ana iya koyar da handle don koyar da accidental operation.

Application of Isolator Switches

1、Machinery and Equipment

Suitable for machinery that requires infrequent connection and disconnection of circuits. The reliable isolation ensures safety during maintenance and operation.

2、Distribution Systems

Used in electrical distribution systems to isolate different sections for maintenance or in case of a fault. Ensures the safety of personnel and equipment.

3、Switchgear and Control Panels

Integral to switchgear and control panels for safe isolation of circuits. Ensures that operators can safely work on electrical panels without the risk of electric shock.

4、Motor Control Centers

Provides isolation for motor control circuits, allowing safe maintenance and operation. Essential in industrial environments where motor control is critical.

5、Photovoltaic Systems

Used in photovoltaic systems to isolate parts of the system for maintenance, ensuring safety and reliability in renewable energy setups.
