No Connection and Split Type Electronic Watthour Meter

摘要

The present invention removes the body of the electricity meter when the electric wire is penetrated into the electricity meter in the connectionless electricity meter and inserts the electric wire through it, and the detection of the electric current is caused by inserting the electric wire into the current sensor having the detachable structure installed in the body. The voltage detection is directed to a connectionless and body-separated electronic watt-hour meter in which a voltage branch screw installed in the body is partially inserted into the covering of the wire to branch the voltage by contacting the wire.;The structure of the connectionless and body-separated electronic electricity meter is largely divided into an upper body 22 and a lower body 21. The lower body 21 is provided with low voltage wires 43 and 44 for supplying power to the load by passing through the body of the electricity meter in the form of a single wire without cutting the wires that pass through the current sensor. A wire fixing device (23, 24) having current sensors (31, 32) having a separable structure so as to surround the inner core thereof, and having voltage branch screws (33, 34) having a function of detecting a voltage. , 25, 26). The upper body 22 includes an electronic circuit board 40 and a display device 47 that receive electric current and voltage values detected by the lower body 21 to calculate the amount of power and display the amount of power. A connection line 39 is formed between the upper body and the lower body to connect the electronic circuit board at the current sensor and the voltage branch screw.
