Clock Source
(
- Timing Server
,
- Beidou Network Time Calibration
,
- Beidou time synchronization products
)
- Introduction
. Produced by Jinan Weishang Electronics Co., Ltd.
Clock source
- Utilization
(
- Global Positioning System
)
- Second synchronized time signals sent by satellites
,
- Provide accurate information to various automation devices in power systems and other industries synchronized time signal.
- The device is mainly used in the following aspects:
- For power grid automation devices such as fault recorders, microcomputer relay protection and safety automatic devices, telecontrol and microcomputer monitoring systems, events Devices such as recorders provide time signals.
- Standard clock used for frequency monitoring
,
- That is, the difference between the power frequency clock and the standard time is used to compare the system frequency error accumulation in scheduling.
- The synchronous clock used for phase measurement uses a clock device to synchronize the sampling pulses. The synchronization error is very small, which can ensure the accuracy of the phase measurement.
- Used for testing relay protection devices and inspecting line longitudinal protection (high-frequency phase difference protection devices).
- Used for fault location
,
- It especially creates conditions for the development of devices based on the principle of double-ended traveling wave distance measurement.
- The device mainly has the following features
:
- High time accuracy
,
- The output second pulse accuracy reaches microsecond level.
- Powering on or off has no effect on the output
-.
- High signal reception reliability
,
- Not restricted by regional conditions such as power stations.
- Settable seconds, minutes and hours synchronized pulse output
,
- And can output time information through the serial port
,
- Can be easily selected by various automation devices.
- All signal outputs of the device are photoelectrically isolated
,
- It has strong anti-interference ability and complies with the standard of "General Technical Conditions for Static Relay Protection Devices and Safety Automatic Devices" Require.
- The device has a variety of serial information output and interaction methods to meet the different signal utilization needs of different users.
- With accident alarm function, power loss alarm and fault alarm each have a pair of relay normally open contact outputs.
- Rack-mounted structure
,
-,
- inch standard chassis, easy to install and use.
