The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises 220V and powers, voltage table feed circuit, reometer feed circuit, voltage table display circuit, reometer display circuit, shunt, slide rheostat and 48V communication power supply to be measured, described 220V energization input is connected with described reometer feed circuit with described voltage table feed circuit respectively, described reometer feed circuit connect cathode output end after described reometer digital indicator and described shunt connect after described slide rheostat with the connection of described voltage table display cathode output end, the cathode output end of described shunt is connected with the cathode output end of described voltage table digital indicator, the power output end of described voltage table feed circuit is connected with the power input of described voltage table digital indicator, the power output end of described voltage table digital indicator is connected with the power input of described 48V communication power supply to be measured.
The beneficial effects of the utility model are:
The utility model departs from the communication power supply power test instrument apparatus that base station band carries test mode, achieve low cost, convenience, intuitively, Power supply belt loading capability test efficiently, achieve the important technology breakthrough at power test after power supply maintenance; The utility model has that structure is simple, cost is low, stable performance and serviceable life longer advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of communication power supply power measuring described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises 220V and powers, voltage table feed circuit, reometer feed circuit, voltage table display circuit, reometer display circuit, shunt, slide rheostat and 48V communication power supply to be measured, described 220V energization input is connected with described reometer feed circuit with described voltage table feed circuit respectively, described reometer feed circuit connect cathode output end after described reometer digital indicator and described shunt connect after described slide rheostat with the connection of described voltage table display cathode output end, the cathode output end of described shunt is connected with the cathode output end of described voltage table digital indicator, the power output end of described voltage table feed circuit is connected with the power input of described voltage table digital indicator, the power output end of described voltage table digital indicator is connected with the power input of described 48V communication power supply to be measured.
Principle of work of the present utility model is as follows:
The utility model to be powered 220V alternating current to proving installation, equipment voltage display circuit and current display circuit start, fictitious load being adjusted to maximum value is connected on the output port of communication power supply, the voltage input end of test instrumentation is connected in parallel on the positive and negative level Wiring port of communication power supply, reometer is connected on the output port then fictitious load being connected on communication power supply.Power to communication power supply input port, this is communication power supply device for testing power voltage table display voltage, reometer display electric current, by adjusting the resistance of slide rheostat, reometer numerical value constantly changes, and calculates output power, also can observe the variation range of voltage table when adjusting output power, contribute to the stability analyzing power supply, also can bake machine test for a long time.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model instructionss and accompanying drawing content are done, is all contained within interest field of the present utility model.
