Description
The GDSCP-1000H is a professional-grade, high-precision portable contact pressure testerexclusively designed for on-site quantitative detection of contact clamping force in disconnecting switches, circuit breakers, vacuum contactors and low-voltage drawer switches in power systems, electrical manufacturing and industrial enterprises. It fully complies with GB 1985-2014, DL/T 486-2010 and IEC 62271-102:2018 standards, adopting advanced strain gauge pressure sensing technology that eliminates the need to disassemble any switch components, enabling direct on-site testing without power outage or mechanical adjustment.
The instrument features an innovative simulated contact integrated sensor whose shape and dimensions exactly match the actual moving contact, accurately reproducing the real contact state between the moving and static contacts. This ensures that the measured pressure is consistent with the actual operating pressure, solving the long-standing problem of inaccurate measurement caused by traditional spring scale methods. The built-in 200+ rated pressure values for mainstream disconnecting switch models automatically compare test results with standard values and display whether they are qualified, eliminating the need for manual lookup of technical manuals.

FAQ
Q: Why is contact pressure measurement so important for disconnecting switches?
A: Contact pressure is the core indicator that determines the conductive performance and mechanical life of disconnecting switches. Insufficient contact pressure will cause increased contact resistance, overheating during operation, spring annealing and contact erosion, forming a vicious cycle that may eventually lead to equipment burnout and power grid accidents. Excessive contact pressure will increase the operating torque, accelerate contact wear and reduce the mechanical life of the switch. Regular contact pressure testing is the most effective means to prevent these failures.
Q: What is the advantage of GDSCP-1000H compared to traditional spring scale measurement methods?
A: Traditional spring scale measurement methods have many disadvantages:
- Unsafe: Operators need to climb to high altitudes to operate, with falling hazards
- Inaccurate: Manual operation leads to large measurement errors, and it is impossible to measure scissors-type disconnecting switches
- Time-consuming: Requires disassembly and reassembly of switch components, taking 30-60 minutes per phase
- No data management: Manual recording of data, easy to make mistakes and difficult to trace
GDSCP-1000H solves all these problems:
- Safe: 10-meter long cable allows ground operation for high-altitude switchgear
- Accurate: Simulated contact design ensures true contact state reproduction, ±1% measurement accuracy
- Fast: No disassembly required, completes one phase test in less than 1 minute
- Intelligent: Automatic data recording, qualified judgment and report generation
Q: What types of switch contacts can GDSCP-1000H test?
A: GDSCP-1000H can test almost all types of switch contacts:
- Disconnecting switches: Knife-type, scissors-type, rotary-type and plug-in disconnecting switches
- Circuit breakers: Vacuum circuit breakers, SF6 circuit breakers and low-voltage circuit breakers
- Contactors: AC contactors, DC contactors and vacuum contactors
- Other contacts: Low-voltage drawer switch contacts, busbar connectors and plug-in terminals
We provide various types of sensors for different contact structures, and can customize sensors according to customer requirements.
Q: How to calibrate the instrument?
A: GDSCP-1000H is calibrated using standard weights or a standard force gauge with accuracy not lower than 0.5 class. The calibration procedure is simple and fast:
- Place the standard weight on the sensor or connect the standard force gauge in series
- Enter the calibration mode in the instrument menu
- Follow the prompts to complete the calibration process
- The instrument will automatically save the calibration coefficient
The instrument should be calibrated once every 12 months according to national metrology requirements.
Q: What is the allowable contact pressure range for disconnecting switches?
A: The allowable contact pressure range varies depending on the switch model, voltage level and current rating. Generally:
- 10kV disconnecting switches: 80N ~ 150N per contact
- 35kV disconnecting switches: 120N ~ 200N per contact
- 110kV disconnecting switches: 150N ~ 250N per contact
- 220kV disconnecting switches: 200N ~ 350N per contact
- 500kV disconnecting switches: 300N ~ 500N per contact
The exact rated pressure value should refer to the manufacturer's technical manual. GDSCP-1000H has built-in rated pressure values for 200+ mainstream switch models, which can be directly called for automatic qualified judgment.
