คำอธิบายสินค้า
HY-8000 satellite time synchronization system is a time synchronization system designed according to "Technical Specifications for Power System Time Synchronization", "East China Power Grid Unified Clock System Technical Specifications" and "Shanghai Power Grid GPS Time Synchronization System Technical Principles and Operation Management Regulations". The main clock of the time synchronization system and the slave clock of the time synchronization system can be grouped or grouped separately. The system uses GPS (Global Satellite Positioning System), Beidou or IRIG-B (DC) codes to send second synchronization signals and time information to various systems and automation devices in the power system (such as dispatch automation systems, microcomputer relay protection devices, Fault recorder, event sequence recording device, telecontrol device, computer data exchange network, lightning location system, etc.) provide accurate time information and time synchronization signals.
Product Usage:
The main uses of HY-8000 satellite time synchronization system are as follows:
1.The system combines the technical characteristics of the United States GPS, China's second-generation Beidou, and Russia's Gronassi and takes into account various related factors related to national security, and realizes multi-source input (second-generation Beidou, GPS, Gronassi, high-precision surveillance Time, IRIG-B code benchmark, etc.), output multi-standard (TTL, empty contact, IRIG-B, differential, serial, network, fiber, etc.), meet multiple devices (system output can be arbitrarily expanded, can meet any scale, any way Requirements for time signals) can provide high precision, high stability, and high security for devices and systems that need to receive clock synchronization signals in systems such as electricity, coal, rail transit, petrochemicals, waterway shipping, post and telecommunications, and related systems. Highly reliable time reference signal.
2. Used as a wall clock for power companies (electricity bureaus) at all levels and their dispatching stations, power plants, substations and other units.
Features:
1. High synchronization accuracy with external synchronization clock signal, the synchronization accuracy is better than ± 0.2μs.
Multi-synchronous source adaptive synchronization technology is adopted, and the synchronization accuracy is better than ± 0.2μs.
2.Use redundant structure
Supports dual Beidou or GPS hot standby and dual IRIG-B hot standby and is equipped with high-precision punctual clock. The main clock of the time synchronization system can be simultaneously connected to Beidou or GPS and one channel of IRIG-B code synchronization signals, which are backup for each other. The time synchronization system can simultaneously access two IRIG-B code external synchronization signals from the clock, which are standby for each other. Both the main clock and the signal expansion device can adopt redundant devices to ensure the reliability and stability of the GPS time synchronization system.
3. Modular design, multiple output interfaces, flexible and convenient to use.
It can output IRIG-B (AC) code, IRIG-B (DC) code that meets the IEEE STD 1344-1995 standard, as well as definable time, minute, and second pulse empty contacts and time message information. Each 12 channels is a group. 2U devices can output up to 60 channels, and 4U devices can output up to 156 channels.
It adopts 2U or 4U 19 "standard chassis, which can be grouped separately, and supports optical fiber or cable cascading input and output, which provides convenience for future expansion of satellite time synchronization signals and facilitates maintenance and management.
4. Dual CPU parallel processing time message output technology
The time message output uses dual-CPU parallel processing technology. The serial message transmission time is the punctual edge of the second, and the error is not greater than + 0.2ms.
5.High-precision pulse output
The pulse output uses a pulse high-current generating circuit, so that the photoelectrically isolated empty contact can output a high-precision pulse signal with an error of not more than 3 μs.
6, high-precision punctuality clock
Adopt closed-loop control timing technology to achieve high-precision timing clock, OCXO timing accuracy can reach 0.3μs / min, and TCXO timing accuracy can reach 15μs / min.
7, using non-overshoot IRIG-B (AC) code generation technology, to generate high-precision IRIG-B (AC) code, the accuracy can reach 5μs.
8. Support NTP v2, v3, v4 (RFC1119 & 1305) and SNTP (RFC2030), support PTP v2
9, LCD display date and time and external synchronization information, with grid frequency measurement function
10. All signal output ports are optically isolated, and the electromagnetic anti-interference reaches the level IV standard.
11. There are alarm contact outputs that monitor the running status of the device, including power supply disappearance alarm, external synchronization signal disappearance alarm, and the device self-test abnormal alarm.
12. Multi-satellite system access and seamless switching between different systems ensure the safety and reliability of the time service system. Currently supports access to satellite systems such as the second generation Beidou, GPS, and Glonass.
13. Adapt to more networking modes, mutual backup mode, master-slave mode, etc. Flexible and changeable networking mode, suitable for dual clock or multi-clock mutual backup, son-mother clock, etc.
14.The device operation status can be uploaded to the dispatch center through the 104 protocol.
