Background
In the low distribution network power supply system, residual current appears in a low-voltage power supply line due to the reasons of insulation reduction of power facilities, aging of household appliances, non-standard power consumption and the like. The leakage current not only causes energy waste and electric appliance fire, but also causes damage to electric equipment and even personal electric shock accidents. Therefore, the leakage of the equipment in the low distribution network must be effectively monitored and timely debugged.
In the existing circuit residual current inspection, equipment inspection is adopted to find fault points and a current clamp meter is used to measure and search the fault points.
The current clamp meter is called clamp meter for short. The working part of the current transformer mainly comprises an electromagnetic type current meter and a straight-through current transformer. The iron core of the straight-through current transformer is made into a movable opening and is in a pincer shape, so that the straight-through current transformer is named as a pincer ammeter. The clamp meter (clamp meter) is an instrument integrating a current transformer and an ammeter, is an important branch of a digital multimeter, and has the same working principle as the current transformer for measuring current.
The split core type ammeter is formed by combining a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is tightened; the lead through which the current to be measured passes can pass through the open notch of the core without being cut off, and the core is closed after the wrench is released. The current conductor of the circuit under test, which passes through the core, becomes the primary coil of the current transformer, wherein a current is induced in the secondary coil by the current. So that the ammeter connected with the secondary coil has an indication to measure the current of the measured circuit.
When the clamp meter is used, a measured lead is required to be placed at the central position in the jaw to reduce errors, but in actual use, a worker can hardly adjust the measured lead to the central position of the jaw, and particularly for a line at a high position, the measured position of the measured lead is difficult to adjust, so that the measurement error is large.
