Brief description of the drawings
Fig. 1 is the structural representation of the wireless divider of the utility model.
Fig. 2 is the transmitting antenna exciting circuit schematic diagram of the wireless divider of the utility model.
Embodiment
As shown in Figure 1, 2, a kind of wireless divider with grading ring transmitting antenna, including the transmitting of superposed grading ring
Antenna 1, the insulating cylinder 2 positioned at middle part, the voltage signal process part 3 positioned at bottom.
The exit of grading ring transmitting antenna 1 connects the first high-frequency choke inductance L1, plays and hinders wireless signal to pass through
Voltage is measured the effect of device.
The inside of insulating cylinder 2 is provided with high-voltage capacitance C1, low-voltage capacitance C2.
The voltage signal process part 3 includes Metal shielding shell, be provided with it power-frequency voltage signal processing circuit,
Wireless signal transmission circuit.Metal shielding shell is made for the metal material of high conductivity, plays a part of shielding electric field,
Its internal power-frequency voltage signal processing circuit and wireless signal transmission circuit is set to avoid by external electromagnetic interference.Institute
State Metal shielding shell and be provided with ground terminal 4, voltage output external terminal 5, used when being verified for divider.
A kind of wireless divider with grading ring transmitting antenna of the utility model, the work by the way of two-way signaling transmission
Make, as shown in Figure 2.Measured voltage is coupled to voltage acquisition module, voltage acquisition by low-voltage capacitance C2 by transformer T0
The preposition low pass filter of module, on the one hand can avoid passing through the external high frequency interference signal that electric capacity passes over, another
Aspect can hinder the radiofrequency signal to be launched to inject.Wireless signal transmitting module exports radiofrequency signal by high-pass filter
To transformer T0, and it is coupled on high-voltage capacitance C1.Impedance matching circuit is rationally set, makes divider high-voltage capacitance C1 with pressing
With it resonance occurs for the electric capacity of the direct-to-ground capacitance of ring transmitting antenna 1 series connection synthesis, can cause signal high efficiency of transmission.
