Embodiment Construction

[0011] like figure 1 As shown in FIG. 4 , in the detector for measuring the voltage / current of the distribution low-voltage line in the present invention, the body 10 is provided with an upwardly opening groove 13 to house the distribution low-voltage line 12 , and the groove 13 A U-shaped accommodating groove 14 is formed around it, and the body 10 is made of insulating material.

[0012] The U-shaped lower magnetic core 20 is placed in the accommodation groove 14 of the body 10, and the coil 30 is wound on the lower magnetic core 20 through an insulating material, and an induced current is generated by the current flowing in the power distribution low-voltage line 12; The capacitor C1 is connected in parallel to the lead wires L1 and L2 at both ends of the coil 30 to filter noise components. The resistor R1 is connected to the lead wires L1 and L2 at both ends of the coil 30 and connected in parallel to the capacitor C1.

[0013] One end of the ground wire L3 is connected t...

Abstract

A probe for measuring voltage / current of power distribution low voltage line is provided to measure a voltage / current of a power distribution low-voltage line accurately by forming a voltage detection terminal and a current detection coil in a body. A groove admits a power distribution low-voltage line. A main body includes a U-character shape admission groove formed around the groove. A lower core is inserted into the admission groove. A coil detects an induction current by a current flowing in the power distribution low-voltage line. A capacitor filters a noise. A grounding line is connected with the lower core. A voltage detection terminal detects a voltage permitted into the power distribution low-voltage line. A withdrawal line withdraws the detected voltage. An admission groove covers the coil and admits a nut adhered to the voltage detection terminal. A side cover covers the admission groove. An upper cover covers the main body and the side cover. An upper core is settled in the upper cover in correspondence to the lower core.

Description

technical field [0001] The invention relates to a detector for measuring the voltage / current of a distribution low-voltage line, in particular to a detector integrated with a voltage measurement sensor and a current measurement sensor for measuring voltage and current in a distribution low-voltage line. Background technique [0002] There are currently several types of voltage / current measuring detectors for distribution low-voltage lines on the market, but most of them are equipped with voltage measuring sensors and current measuring sensors respectively, which is not only inconvenient to use, but also complicated in structure, which is not conducive to accurate detection. Measure the voltage or current of distribution low-voltage lines. Contents of the invention [0003] The object of the present invention is to provide a voltage measurement sensor and a current measurement sensor integrally formed, which can simultaneously and accurately measure the voltage / current in t...
