LND-110V portable wireless high voltage phase verifier phase verification device remote wireless real voice GPS satellite
The keywords you entered, such as "LND-110V portable wireless high voltage phase verifier" and "GPS satellite," refer to a wireless high-voltage satellite timing remote phase verifier that integrates high-precision satellite timing technology in the power system. This type of equipment is specifically developed to overcome the limitations of traditional phase verifiers in terms of distance and environment, enabling ultra-long-distance and high-precision phase verification.
Combining the features you are concerned about, such as portability, remote wireless, and GPS satellite, here is an overview of the core technical principles and operational specifications of this series of equipment:
1. Core Technical Features
GPS/Multi-mode Satellite Timing: The device is equipped with a six-in-one multi-mode satellite timing module (compatible with BeiDou, GPS, etc.), with timing accuracy as high as less than 30nS. Through joint timing technology, it fundamentally ensures the accuracy of phase verification results, breaking the limitations of distance and environment.
Ultra-long-distance Transmission: In an open ground environment, the ordinary wireless phase verification distance can reach 160m; while in satellite timing phase verification mode, the distance can exceed 500km, greatly facilitating remote phase verification operations across substations and lines.
Real Voice and Intuitive Display: Equipped with a high-definition true-color LCD screen, it can display real-time phase, frequency, vector diagrams, and other data on the same screen; it also features real voice prompts such as "X signal normal, Y signal normal, same phase, different phase," making single-person operation and result judgment simple and intuitive.
Wide Voltage and Dual-mode Phase Verification: Supports full intelligent phase verification from 10V to 550kV. For bare conductors of 35kV and below, direct contact phase verification is possible; for bare conductors above 35kV, non-contact phase verification is adopted, where the detector gradually approaches the induced electric field signal to complete the verification without direct contact, greatly enhancing safety.
2. Special Scenario Operation Specifications (Phase Verification in Basements without Signal)
For complex environments such as basements and underground mines where there is no satellite signal or mobile phone signal, this equipment can use satellite timing mode for phase verification. The specific operation process is as follows:
Ground Timing: First, take the two receivers to an open area, search for satellites, and complete timing (usually set to automatically store time every 5 seconds).
Underground Collection: Bring the two receivers together into the basement for phase verification. During this period, the receivers will automatically store real-time phase angle data every 5 seconds.
Data Comparison: After storing dozens of sets of data, bring the receivers back to the ground, and manually compare the real-time phase angle differences at the same time points in the two sets of data to determine the phase verification result.
⚠️ Key Warning: During phase verification in the basement, the receivers must not be turned off and then on again; otherwise, satellite timing will be interrupted, and you must return to the ground to search for satellite signals and complete timing before continuing operation.
3. Safety Operation Guidelines
Insulation Requirements: When the voltage of the tested line exceeds 600V, it is mandatory to use a qualified telescopic insulating rod. It is strictly forbidden to use this instrument to directly contact bare conductors or busbars above 35kV.
Short-circuit Prevention: During testing, it is strictly forbidden to hook two bare conductors at the same time to avoid the risk of short circuit.
Equipment Maintenance: Before first use, the insulating rod should undergo a withstand voltage test; if the instrument is not used for a long time, it is recommended to charge the battery every 3 months.
💡 Further Assistance
This type of phase verifier integrated with GPS satellite timing function is a core tool for ensuring the safety of large power grid grid connection and switching operations. May I ask what your specific needs are currently:
Technical Parameter Verification: Do you need me to provide a detailed explanation of the satellite synchronization calibration process for this equipment during cross-region (e.g., tens of kilometers apart) substation grid connection?
On-site Operation Guidance: Do you need to understand the specific wiring and non-contact induction operation steps on ring main units, medium-voltage switchgear, or high-voltage overhead lines?
Selection and Compliance Inspection: Do you need to inquire about the periodic insulation rod withstand voltage test standards for this equipment, or understand how to configure the appropriate insulation rod length according to the on-site voltage level (e.g., 110kV)?
