Abstract
Electric power system secondary line wiring intensity testing arrangement. The secondary small wire is clamped by a sharp-mouth clamp for detection, the secondary small wire is easily broken by the detection method, and meanwhile, an operator cannot master the pulling force when pulling, so that the conditions that the wiring strength cannot be detected frequently and the wiring is broken due to overlarge pulling force are caused. The utility model discloses the constitution includes: i-shaped pull rod (3), two splint (2), shell (4) and spring dynamometer (6), two splint respectively with the I-shaped pull rod articulated, two the splint between be connected with spring (10), the I-shaped pull rod insert the shell in and with shell sliding fit, the spring dynamometer be located the shell in and with shell sliding fit, the tensile force head (9) of spring dynamometer on the couple hang the link (8) of I-shaped pull rod on. The utility model is used for secondary line wiring strength test.
Description
The technical field is as follows:
the utility model relates to an electric power system secondary line wiring intensity testing arrangement.
Background art:
the secondary equipment is low-voltage electrical equipment used for monitoring, controlling, measuring, adjusting and protecting the working conditions of an electric power system and primary equipment, and comprises a measuring instrument, a control and running condition monitoring signal of the primary equipment, an automatic monitoring system, a relay protection and safety automatic device, communication equipment and the like. The secondary devices are connected together through secondary small wires according to certain functional requirements to form a secondary wiring, or called a secondary circuit, which is an essential important component for ensuring safe production, economic operation and reliable power supply of an electric power system.
In order to guarantee the operation of secondary equipment, the wiring strength of a secondary small wire is usually required to be tested, the traditional secondary small wire detection mode is that the secondary small wire is clamped by a sharp-mouth clamp for detection, the secondary small wire is easily clamped and broken by the detection mode, the wiring is required to be conducted again, the working efficiency is low, meanwhile, an operator cannot master the pulling force when pulling, and the situation that the wiring strength cannot be frequently detected and the wiring is broken due to overlarge pulling force is caused.
The utility model has the following contents:
the utility model aims at providing an electric power system secondary line wiring intensity testing arrangement.
The above purpose is realized by the following technical scheme:
the utility model provides an electric power system secondary line wiring intensity testing arrangement, electric power system secondary line wiring intensity testing arrangement include I-shaped pull rod, two splint, shell and spring dynamometer, two splint respectively with the I-shaped pull rod articulated, two the splint between be connected with the spring, the I-shaped pull rod insert the shell in and with shell sliding fit, the spring dynamometer be located the shell in and with shell sliding fit, the overhead couple of pulling force of spring dynamometer hang the link of I-shaped pull rod on.
The testing device for the wiring strength of the secondary line of the power system is characterized in that one end, far away from the spring, of each clamping plate is provided with a semicircular groove, and the semicircular grooves of the two clamping plates are opposite to each other.
The testing device for the wiring strength of the secondary line of the power system is characterized in that a rubber pad is bonded in the semicircular groove.
Has the advantages that:
1. the utility model discloses a carry out the centre gripping with the circular structure that the semicircle recess of two splint formed to the secondary line, it has the rubber pad to bond in the semicircle recess simultaneously, can prevent to press from both sides absolutely to the secondary line.
2. The utility model discloses when the pulling, with the handle part of hand pulling spring dynamometer, the pulling force that spring dynamometer shows simultaneously can be controlled the pulling force of pulling the little line of secondary, prevents that the little line of secondary from being broken by the tension.
3. The utility model discloses can set for secondary xiao liang wiring intensity pulling force value, reach the pulling force back secondary xiao liang of regulation when the pulling and do not broken and also not pulled flexible and show that wiring intensity is qualified, prevent that the too big and undersize condition of pulling force from appearing.
Description of the drawings:
FIG. 1 is a front view of the present invention;
FIG. 2 is a schematic view of the internal structure of the present invention;
FIG. 3 is a schematic structural view of the clamping plate and the I-shaped pull rod;
FIG. 4 is an enlarged view of portion A of FIG. 2;
in the figure: 1. a semicircular groove; 2. a splint; 3. an I-shaped pull rod; 4. a housing; 5. opening the gap; 6. a spring load cell; 7. a handle; 8. hanging a ring; 9. a tension head; 10. a spring; 11. and (7) a rubber pad.
The specific implementation mode is as follows:
example 1:
a testing device for the wiring strength of a secondary wire of an electric power system comprises an I-shaped pull rod 3, two clamping plates 2, a shell 4 and a spring dynamometer 6, wherein the two clamping plates are respectively hinged with the I-shaped pull rod, form a clamping structure, a spring 10 is connected between the two clamping plates, the I-shaped pull rod is inserted into the shell and is in sliding fit with the shell, the shell is in a hollow cylindrical shape, the spring dynamometer is positioned in the shell and is in sliding fit with the shell, the spring dynamometer is also cylindrical, the spring dynamometer is in sliding fit with the inside of the shell, a hook on a tension head 9 of the spring dynamometer is hung on a hanging ring 8 of the I-shaped pull rod, and a notch 5 is formed in the shell and used for observing the numerical value displayed by the spring dynamometer.
Example 2:
according to embodiment 1 of the testing device for the wiring strength of the secondary line of the power system, a semicircular groove 1 is formed in one end, away from the spring, of each clamping plate, and the semicircular grooves of the two clamping plates are opposite.
Example 3:
according to the testing device for the wiring strength of the secondary line of the power system in the embodiment 1 or 2, the rubber pad 11 is bonded in the semicircular groove.
The working principle is as follows: when using, separately make the secondary xiao lin be located the semicircular groove of two splint with two splint, then two splint carry out the centre gripping to the secondary xiao lin under the spring action, the secondary xiao lin can prevent to produce the injury to the secondary xiao lin in being in circular structure, then hold the shell and rotate it, make the opening position be in the demonstration scale department of spring dynamometer, then pull handle 7 is held to another hand, stimulate the spring dynamometer, spring dynamometer pulling I shape pull rod in the pulling, the I shape pull rod slides in the shell, make and stimulate the secondary xiao lin, after the pulling force that the spring dynamometer shows reaches the pulling force of regulation, the secondary xiao lin is not broken, do not become flexible simultaneously, it is qualified to express the wiring intensity.
