Powerful Vacuum Electrical Sectionlizer AC Remote Control
Automatically Operated With High Voltage Vertical Hookstick
Product Description:
The ZW20-12(F) vacuum electrical sectionlizer is a new product that
combines multiple functions into a single intelligent device. It
incorporates the capabilities of a vacuum breaker, vacuum load
switch, recloser, and sectionalizer, offering versatility and
efficiency in various applications.
The main components of the Boundary Load Switch include a vacuum
breaker, a CH-40 controller, and an external voltage transformer.
The vacuum breaker ensures reliable interruption of the circuit,
while the CH-40 controller provides advanced protection, control,
and communication functions. An external voltage transformer, which
is optional for distribution automation line ring networks, can be
utilized for bilateral PT (potential transformer) connections.
This product finds widespread use in 10kV and 13kV city and rural
power grid space ring networks. It serves as a disconnecting
switch, contact switch, and automatic switch device for line load
deployment in ring networks. Additionally, it can function as a
boundary switch (commonly known as a watchdog) in branch power
supply lines, as well as reclosers and sectionalizers in overhead
distribution networks.
The vacuum electrical sectionlizer offers remote management
capabilities, enabling efficient monitoring and control. It
incorporates protection and control functions along with
communication features, facilitating seamless integration into
distribution automation systems.
The device employs reliable detection and judgment mechanisms,
including the ability to detect mA-level zero-sequence current and
short-circuit currents between phases. This allows for automatic
removal of single-phase grounding faults and phase-to-phase
short-circuit faults, enhancing the system's fault management
capabilities.
The main switch of the vacuum electrical sectionlizer utilizes
vacuum arc technology, while the insulation system incorporates SF6
and N2 mixed gas insulation. The product incorporates gas sealing,
explosion-proof, and insulation system technologies from Japan,
Germany, and France, ensuring excellent overall sealing
performance. The internal compartment is filled with SF6 and N2
mixed gas, which prevents leakage and ensures the device's
performance remains unaffected by the external environment.
The spring operating mechanism of the Boundary Load Switch is
designed with miniaturization and performance optimization in mind,
resulting in higher action reliability compared to traditional
spring mechanisms. This design improvement enhances the overall
operational efficiency and lifespan of the device.
The GW9-10 vertical hookstick is an electrical switch that is
designed to isolate a section of an electrical network or system
from the rest of the system for maintenance or repair purposes. It
is typically used in high voltage power transmission and
distribution systems.
The switch is designed to open and close under normal or abnormal
conditions, such as a fault or overcurrent. When the switch is
open, it physically disconnects the section of the system from the
rest of the network, preventing the flow of electricity to that
section.
High voltage disconnect switches are typically designed to operate
at voltages between 600 volts and 765,000 volts, and they can be
operated manually or automatically. They are typically installed in
substations or on power poles, and they are an important component
of the electrical grid infrastructure.
Double effect of using when GW9-10 series isolator swich can be
used with the vacuum circuit breakers.

Structure:
1.Microcomputer Relay Protection and Monitoring: The ZW20-12
circuit breaker features a microcomputer-based relay protection and
monitoring device as its controller. This advanced technology
allows for precise and intelligent fault detection, analysis, and
control, improving the overall performance and reliability of the
circuit breaker.
2.Weathering and Condensation Resistance: The circuit breaker is
designed to withstand natural weathering and condensation. It
incorporates robust materials and protective measures to ensure
reliable operation even in harsh environmental conditions,
enhancing its durability and longevity.
3.Aviation Connector Connection: The utility model of the ZW20-12
circuit breaker is connected to the switch body through an aviation
connector. This type of connector offers secure and reliable
connections, minimizing the risk of loose or faulty connections,
and ensuring stable communication and control between the
controller and the switch body.
4.High Connection Reliability and Protection Level: The circuit
breaker provides good connection reliability, ensuring consistent
and secure electrical connections within the system. Additionally,
it offers a high protection level, safeguarding the internal
components and electrical circuitry against external factors such
as dust, moisture, and physical damage.
5.Analog Input Channels: The controller of the ZW20-12 circuit
breaker includes four analog input channels. These channels monitor
various electrical parameters, including A phase current, C phase
current, sequence current, and BC phase voltage. Real-time
monitoring and comparison of these values with pre-set thresholds
allow for accurate fault detection and appropriate action.
6.Fault Detection and Treatment: The controller continuously
monitors the electrical parameters and compares them with fixed
values to detect line faults. Upon detecting a fault, the
controller initiates the corresponding treatment, such as tripping
the circuit breaker or activating protective measures, ensuring
efficient and timely
Applicaiton
1.Disconnecting Switch and Contact Switch: The ZW20-12(F) circuit
breaker can be used as a disconnecting switch or contact switch in
the ring network configuration of power distribution systems. It
