Abstract
The invention provides a method for electric device and instrument terminal strip protection and relates to the technical field of electric device and instrument safety protection. The method for electric device and instrument terminal strip protection solves the problem that bodies of electric devices and instruments are intact but are prone to wasting due to the fact that line connecting terminals of the electric devices and line connecting terminals of the instruments are seriously damaged in electrician skill training in higher vocational colleges and secondary vocational schools. The method for electric device and instrument terminal strip protection is characterized in that a traditional line connecting mode of the electric device and the instrument is changed to a terminal strip indirect line connecting mode, namely an auxiliary contact terminal of the electric device and an auxiliary contact terminal of the instrument are directly and respectively connected to a terminal strip, and the terminal strip is connected with lines by a student. Each electric device or each instrument is provided with one line connecting terminal strip and each electric device or each instrument and one line connecting terminal strip are installed on the same substrate, so that each electric device with the terminal strip or each instrument with the terminal strip is formed. In training, each electric device with the terminal strip or each instrument with the terminal strip is placed on a training operation platform by the student for circuit installation and debugging. According to the method for electric device and instrument terminal strip protection, the service life of each electric device and the service life of each instrument are prolonged by over 10 times, the student can know and master the electric devices and the instruments conveniently, and the student can master the use technology of the electric devices and the instruments.
Description
Technical field
The present invention relates to the technical field of a kind of electrical equipment and instrument safety protection.
Background technology
Present domestic Higher Vocational College and middle duty school obtain class professional qualification certificates such as middle and high level maintenance electrician for making the student, all must carry out circuit Installation and Debugging technical ability real trainings such as Motor Control, ammeter measurement to the student.In the real training, measurement instrument such as electrical equipment such as A.C. contactor, AC relay, time relay and watt-hour meter, reometer, voltage table is all essential.The connection terminal of their outsides more is to use frequently, thereby damages easily.Especially electrical equipment such as A.C. contactor, AC relay, the time relay, the easier bad silk of the short and small screw rod of its auxiliary contact wiring.Though so that electrical equipment and meter body are intact, its connection terminal is badly damaged, causes entire device or monoblock instrument to go out of use.For addressing this problem, some school is forced to use practical traning platform.This estrade generally all is installed in electrical equipment and instrument within its panel, on the binding post on the panel that only connection terminal gone between for the use safety of protection electrical equipment and instrument.Though this practice has been protected the use safety of electrical equipment and instrument, the student loses understanding and is familiar with their chance, and this has reduced the practice-training teaching quality to a certain extent.At present, though the domestic people of having is seeking to protect the use safety of electrical equipment and instrument always, can the practice-training teaching quality not had influence or influence little method again, it be little to produce effects.The present invention changes traditional electrical equipment and the direct mode of connection of instrument into the terminal row indirect mode of connection, is intended to prolong at double electrical equipment and the serviceable life of instrument in real training, and guarantees practice-training teaching quality conscientiously by their.
Summary of the invention
Purpose of the present invention
Be to avoid in the real trainingThough electrical equipment and meter body are intact; but its connection terminal is badly damaged, the phenomenon that causes entire device or monoblock instrument to go out of use, and the guard method of a kind of electrical equipment and terminal row is provided; prolong their serviceable life in real training at double with this, and guarantee the practice-training teaching quality conscientiously.
For achieving the above object, the technical solution used in the present invention is: change traditional electrical equipment and the direct mode of connection of instrument into the terminal row indirect mode of connection.Namely earlier electrical equipment and instrument terminals are wired to earlier on the terminal row, the student carries out wiring to terminal row more then.Each electrical equipment or instrument have connecting terminal block separately, and they all are installed on the same base plate, form electrical equipment or the instrument of a band terminal row.In real training, the student can be placed on them and carry out circuit installation and debugging on the real training operator's console.The A.C. contactor of band terminal row as shown in drawings.This practice not only makes the connection terminal of electrical equipment and instrument be effectively protected; prolong their serviceable life more than at least 10 times; and be beneficial to the student and understand and be familiar with their principle and using method, this operation technique for student's study and grasp electrical equipment and instrument is highly beneficial.This technology is through the practical application for many years of certain institute, and its economic benefit and teaching benefit are all fine.
The invention has the beneficial effects as follows: overcome former
In the real trainingThough electrical equipment and meter body are intact, but the shortcoming that causes entire device or monoblock instrument to go out of use because its connection terminal is badly damaged, not only prolonged electrical equipment and instrument serviceable life more than at least 10 times, and for student's study with grasp the condition that the operation technique of electrical equipment and instrument is provided convenience.
Below the invention will be further described by accompanying drawing:
Accompanying drawing is a kind of A.C. contactor synoptic diagram with terminal row.Among the figure, the main contacts of A.C. contactor is connecting terminal row not, and Chang Kai and normally closed auxiliary contact connecting terminal row all.
Embodiment:
Hunan Metallurgical Professional Technology College has nearly 600 person-times student to participate in electrician's technical ability real training every year.This institute has been equipped with 40 cover electrical equipment and instrument for implementing this real training.Because electrical equipment and meter body therefore often occur and well but because terminal damage be forced to discard at least more than more than 1200 times connection terminal every year of electrical equipment and instrument.For addressing this problem, this institute forms electrical equipment and the ammeter of band terminal row earlier with the contact of the auxiliary contact of electrical equipment such as A.C. contactor, AC relay and ammeter connecting terminal row all, and the student carries out wiring with electrical equipment and the ammeter of reincarnate more then.This method prolongs electrical equipment and instrument serviceable life more than 10 times at least, has guaranteed the practice-training teaching quality simultaneously.
Claims (2)
1. an electrical equipment and instrument terminals row guard method; it is characterized in that changing traditional electrical equipment and the direct mode of connection of instrument into the terminal row indirect mode of connection; namely earlier directly be wired to electrical equipment and instrument terminals on the terminal row; the student carries out wiring to terminal row more then; each electrical equipment or instrument have connecting terminal block separately; they all are installed on the same plank, form electrical equipment or the instrument of a band terminal row.
2. described according to claim 1, the auxiliary contact connecting terminal of electrical equipment row, and main contacts connecting terminal row not, the terminals of instrument are connecting terminal row all.
