12-channel circuit breaker dynamic characteristic tester waterproof standard circular
Regarding the "12-channel circuit breaker dynamic characteristic tester waterproof standard circular" you mentioned, it seems that multiple different equipment concepts or parameters have been mixed together. To help you clarify your requirements, I will break down and explain as follows:
1. About the "12-channel circuit breaker dynamic characteristic tester"
This is a very core high-voltage test equipment in the power system (also known as a high-voltage switch mechanical characteristic tester).
Core functions: Supports synchronous acquisition of 12 break contacts (metal main contacts), and can measure the circuit breaker's opening/closing time, same-phase and inter-phase synchronization, bounce, travel, speed, and opening/closing coil current waveforms in one operation.
Applicable equipment: Suitable for 10kV to 1000kV SF6 switches, GIS combined appliances, vacuum switches, oil switches, etc.
Industry status: Currently, mainstream manufacturers (such as Wuhan Qianxu Electric, Wuhan Moen Intelligent, etc.) can provide 12-channel models with built-in programmable DC power supply, strong electromagnetic anti-interference (live testing in 500kV substations), and intelligent waveform analysis functions.
2. About the "waterproof standard"
Industry status: Circuit breaker dynamic characteristic testers are high-precision electronic measuring instruments, usually required to be used indoors or in substation control rooms. Their conventional protection level is mostly dustproof and drip-proof. There are very few dedicated "waterproof standards" or IP67/IP68 level waterproof requirements in the industry. If your usage environment has serious moisture or condensation issues, it is recommended to dehumidify the environment before testing, or consult the manufacturer for a custom high-protection-level enclosure.
3. About the "circular"
Concept clarification: The main unit of a circuit breaker dynamic characteristic tester is usually in the shape of a square suitcase or a portable industrial computer, not circular.
Possible misunderstanding: The "circular" you mentioned is most likely referring to the "rotary sensor" (also called an angle sensor) that comes with the instrument. The mounting end or shaft part of this sensor is circular, specifically used to install on the rotating main shaft or crank arm of the circuit breaker to measure the switch's travel and speed.
