ZW20 Intelligent Vacuum Circuit Breaker, manufactured by Chuanlong

1. Overview of Chuanlong Electric's ZW20-12 Vacuum Circuit Breaker

ZW20 Vacuum Circuit Breaker is a circuit breaker with SF6 gas insulation and vacuum arc extinguishing. It is one of the main product lines of Zhejiang Chuanlong Electric Co., Ltd. The ZW20 Vacuum Circuit Breaker with watchdog sectionalizing switch, when paired with an intelligent controller, has functions such as manual energy storage, manual opening and closing, electric opening and closing, remote opening and closing, overcurrent protection, instantaneous trip protection, ground protection, reclosing, self-diagnosis, event recording, historical fault query, and status uploading. It can achieve automation and all-weather monitoring and management of distribution lines, and is very suitable for use in large and medium-sized users and urban and rural distribution networks. It is a must-have supporting product in the future smart grid system.

For purchasingZW20-12, zw20-12f series vacuum circuit breakers, and obtaining more instruction manuals, technical data, and purchasing information of ZW20 sectionalizing vacuum circuit breakers, please contact us directly.

Common purchasing configurations of ZW20 Vacuum Circuit Breaker are:

Carbon steel powder-coated shell + Electric operating mechanism + With zero-sequence ground protection + Voltage transformer + Watchdog intelligent controller;

Carbon steel sprayed plastic shell+Electric operating mechanism+With zero-sequence grounding protection+Voltage transformer+Watchdog intelligent controller+Isolating switch;

Stainless steel shell+Electric operating mechanism+With zero-sequence grounding protection+Voltage transformer+Watchdog intelligent controller;

Stainless steel shell+Electric operating mechanism+With zero-sequence grounding protection+Voltage transformer+Watchdog intelligent controller+Isolating switch;

Of course, there are also some customers with low requirements. They use manual operating mechanisms instead of the operating mechanisms mentioned above. Then the configuration at this time is

Carbon steel sprayed plastic shell or stainless steel shell+Manual operating mechanism+Instantaneous overcurrent protection+Optional isolating switch.

Therefore, we hereby suggest that customers inform us of the above information when making purchases.

2. Composition of ZW20 series vacuum circuit breakers

ZW20F-12 type high-voltage outdoor sectionalizing switch is mainly composed ofZW20F-12type vacuum circuit breaker body, FDRcontroller and external voltage transformer. The three parts are electrically connected through aviation sockets and outdoor sealed control cables. According to the user's management requirements, an on-site remote control device and operating software (“GPRS”Remote or “GSM” SMS)

3. zw20 Main functions of the sectional vacuum circuit breaker

Produced by Zhejiang ChuanlongZW20 vacuum circuit breakerhas functions such as manual energy storage, manual opening and closing, electric opening and closing, remote control opening and closing, overcurrent protection, instantaneous trip protection, grounding protection, reclosing, self-diagnosis, event recording, historical fault query, status uploading, etc. It can realize the automation, all-weather monitoring and management of the distribution line, and is very suitable for use in large and medium-sized users and urban and rural distribution networks. It is a must - choose supporting product in the future smart grid system.

4. zw20 - 12 Structure of the vacuum circuit breaker

Manufactured by Zhejiang Chuanlong Electric Co., Ltd.ZW20 vacuumThe main body structure of the circuit breaker consists of an insulation system, an operating system, a conductive system, a sealing system and a measurement system.

? The conductive system consists of incoming and outgoing conductive rods, conductive clamps, copper flexible connections and vacuum interrupters. It has a strong current - carrying capacity, and its arc - extinguishing and breaking performance are better than similar products.

? This product adopts a relatively mature sealing structure at present. The contact parts between the rotating parts and the shell are sealed by means of grooving plus sealing rings and stamped - formed grooves to ensure good air - tight performance. The main circuit, secondary components and operating mechanism are all sealed in SF6 gas (zero gauge pressure), which improves the electrical operating performance of the switching elements.

? This product uses SF6 gas insulation inside the shell, which greatly improves the electrical safety performance of the internal structure of the switch. The incoming and outgoing line bushings are integrally cast with epoxy resin and silicone rubber. The A and C phases adopt outward - flaring corner - type bushings, which increases the phase spacing, ensures good external insulation, has excellent performance, and is a maintenance - free product.

?PrecisequeThe precise measurement system consists of *** current transformers and zero-sequence transformers. For this product, a current transformer with an accuracy class of 1 and a transformation ratio of 200 - 600/5 is installed at each of the incoming line ends of phase A and phase C to detect the operating current of the line in real-time, ensuring the quality of line operation. A zero-sequence transformer with an accuracy class of 1 and a transformation ratio of 20/1 is installed on the three-phase outgoing line side. It can detect the ground current in the range of 0.2A - 6A and has a good linear relationship, ensuring the accuracy of monitoring data.

?The circuit breaker body can be installed by pole-mounted hoisting or pedestal installation. The installation is convenient and flexible, greatly increasing the options for installation methods. The sectionalizing controller is installed under the circuit breaker in a place convenient for viewing. The secondary wiring is connected to the sectionalizing circuit breaker through a cable. The power transformer (voltage PT) can be placed side by side with the circuit breaker or above the switch body.

?This device has the functions of electric automatic energy storage, manual energy storage, manual opening and closing, and electric opening and closing. It also has the function of remote opening and closing, meeting the operation requirements of different users.

?An explosion-proof device is installed on the top of the box. Even if an accident, discharge, or short-circuit fault occurs inside the device body, no high-temperature gas or splashes will leak out.
