Description

Connecting method for electrified lead

Technical Field

A connection method of an electrified lead relates to the field of installation of the electrified lead and aims to solve the connection problem of the electrified lead and the problem of repairability reconnection of a circuit broken circuit after the electrified lead is broken.

Background

The project aims at the connection of an electrified lead and the repairable connection problem of a broken wire in a power line in daily life, relates to the background technology of how to correctly use two aspects of an electroscope and a wire connection method, and describes the background technology from three aspects of the use of the electroscope, the cutting of a copper core wire insulating layer and the connection of the wire.

Structure, principle, function and using method of test pencil

The structure of the test pencil: the test pencil is also called a low-voltage electroscope or a test pencil, and is usually called as a test pencil for short. The test pencil is an auxiliary safety tool commonly used by electricians, is used for checking whether a conductor below 500V or shells of various electric equipment are electrified, is simple and convenient to operate, can be carried about, and has two kinds of common test pencils.

The first common test pencil is a pen-type test pencil which is made into a small screwdriver structure, and the neon tube test pencil consists of a pen point type working contact, a resistor, a neon tube, a pencil holder, a spring, a hanging nose and the like.

The second common test pencil is a digital test pencil which is also called a display digital test pencil, the test pencil is composed of a nib-type working contact, a pencil body, an indicator light, a voltage display, a voltage induction detection button, a voltage display detection button, a battery and the like, the voltage induction detection button is an electrode for directly measuring voltage induction, and the voltage display detection button is an electrode for directly measuring and displaying the number of voltages.

The working principle of the test pencil during test is as follows: when in test, an operator can form a loop even wearing an insulating shoe (boot) or standing on an insulator, because the leakage current of the insulator and the capacitance current between the human body and the ground are enough to enable the neon tube to glow, the electroscope can glow as long as a certain potential difference exists between the charged body and the ground; when the digital electroscope is used for measuring the alternating current, the induction detection button is not pressed, and when the pen point is inserted into the photo wire hole, the indicator light is lightened, and the alternating current is indicated; if the voltage display is needed, the direct detection button is pressed, and the number displayed by the digital electroscope is the measured voltage value.

The test method of the test pencil comprises the following steps: when the test pencil is used for testing the electrified body, an operator touches the central screw of the metal body at the tail of the test pencil by hand and contacts the tested electrified body by the working contact, at the moment, the electrified body experiences the working contact of the test pencil, the resistor, the neon tube, the human body and the ground to form a loop, and when the tested body is electrified, current passes through the loop to enable the neon tube to glow; if the neon tube is not bright, the object to be measured is not charged.

Test notes using test pencil: before testing, the test should be carried out on a charged body with electricity, and the test pencil can be used after being proved to be intact; a worker needs to develop a good habit of firstly testing electricity by using an electricity testing pen and then working; when the test pencil is used, the insulating shoes and boots are preferably worn; when testing electricity, the worker should keep stable operation to avoid short circuit caused by error touch; when testing is carried out in a place with bright light, careful test and observation in a dark place are needed to avoid misjudgment caused by unclear sight; some equipment often leads to the electrification of the shell due to induction, the neon tube of the test pencil is also lightened during testing, and error judgment is easily caused; when the low-voltage electroscope is used, the measurement on a charged body exceeding 500V is not allowed; if the indicator light of the digital test pencil is not on, the battery is replaced firstly, then the test pencil is used, so that the measurement by the digital test pencil without the power supply is prevented, and the wired circuit is mistakenly treated as the wireless circuit, so that danger is caused.

Second, tool and method for cutting insulating layer of conducting wire

The background technology of connecting wires is to cut the insulation layer of the wire first and then connect the core wire of the wire, and there are several common methods for cutting the wire.

Before the insulated wire is connected, a section of the insulation layer from the end of the wire to the inside must be stripped, and the stripping and cutting length of the insulation layer is different due to different joint modes and different sections of the wire; the method for stripping and cutting the insulating layer is correct, and generally comprises a single-layer stripping method, a sectional stripping method and a beveling method, wherein the single-layer stripping method is generally used for the plastic insulating wire, the sectional stripping method and the beveling method are adopted for the rubber insulating wire, and the wire core is not damaged when the insulating layer is stripped and cut.
