Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.
As shown in Figure 1, wireless high-voltage phasing tester, be made up of transmitter module X, transmitter module Y, hand-held set and insulating bar, described transmitter module X and transmitter module Y is installed on insulating bar respectively, described hand-held set comprises wireless receiving module, power control circuit, LCD liquid crystal display and button, the wireless receiving module of described hand-held set is connected by wireless signal with between transmitter module X and transmitter module Y, and described button comprises power key, backlight key and voice key.
The utility model wireless high-voltage phasing tester design concept is as follows:
If reference signal is: U
1(t)=Asin (ω t
1),
Measuring-signal is: U
2(t)=Asin (ω t
2-φ),
U
1t the moment of () zero passage is t
1, U
2t the moment of () zero passage is t
2,
Work as U
1(t)=U
2ω t can be obtained during (t)=0
1=ω t
2-φ=n π, gained phase differential is:
φ＝ωt
2-ωt
1＝2π(t
