For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0034] Please see Figures 1 to 4This application provides a multi-purpose CT terminal shorting tool, comprising: a shorting pen 10, a contact 20, a retainer 30, and a shorting bar 40; the shorting pen 10 includes a sleeve 11 and a pen barrel 12; one end of the pen barrel 12 is slidably fitted into the sleeve 11; a first insulating cover 13 is provided on the pen barrel 12, and a shorting hole 14 is provided on the pen barrel 12; the contact 20 is detachably disposed at the other end of the pen barrel 12; the retainer 30 is made of an elastic material, and a plurality of parallel and spaced grooves 31 are provided on the retainer 30; a plurality of short contact fingers 41 are provided on the shorting bar 40, and the shorting bar 40 is electrically connected to a grounding wire 42; the short contact fingers 41 are used to insert into the shorting hole 14 so that the shorting bar 40 is electrically connected to the shorting pen 10.

[0035] The retainer 30 is a flexible soft rubber retainer; the jumper 10 can easily fit into the groove 31, which is designed with commonly used terminal spacing dimensions. Once fixed, the jumper 10 can be pulled out and inserted simultaneously in a row when needed, greatly reducing workload. For conventional and neat CT lead terminal block designs, the spacing of the jumper 10 can be adjusted according to specific circumstances. For example, it can be like... Figure 4 The middle section is adjusted to use two shorting pens.

[0036] Specifically, the pen holder 12 can slide along the sleeve 11 to adjust its length, making it easy for maintenance personnel to adjust the shorting pen 10 to a suitable length. Both the pen holder 12 and the sleeve 11 can be made of insulating silicone rubber for insulation. The groove 31 on the holder 30 can be cylindrical, facilitating the insertion and fixing of the shorting pen 10 to the same CT terminal block area, thus simplifying disassembly and organization.

[0037] The first insulating cover 13 can also be made of rubber and can be a hemispherical shape with a diameter of about 9mm. The first insulating cover 13 can fit tightly against the terminal socket for the contact 20 to be inserted, avoiding short circuits caused by metal wires or terminal wires crossing each other around the terminal socket. In addition, it can prevent electric sparks or electrostatic induction from burning the operator's fingers even when the terminal socket discharges.

[0038] The shorting bar 40 can be made of copper conductor and is electrically connected to the shorting contact finger 41. The shorting contact finger 41 is used to insert into the shorting hole 14 to realize the electrical connection between the shorting bar 40 and the inside of the pen barrel 12, which serves to short-circuit and lead out to the grounding wire 42, that is, the CT shorting terminal is grounded after being shorted at the same time.

[0039] It should be noted that the inner edge of the shorting hole 14 is a copper connector socket, mainly used for shorting the contact fingers 41. It can be used to connect shorting wires and test shorting wires, and can also be used as a monitoring and acquisition output terminal outlet. When the shorting probe 10 is inserted into the terminal block and covers the metal part of the terminal, it is also convenient to use a multimeter probe to insert into the shorting hole 14 to measure the voltage signal of this terminal.

[0040] In one embodiment, see Figure 2 The contact 20 includes multiple contacts; the contact 20 is straight or bent.

[0041] The contact 20 can be made of copper. Different shapes of contact 20 can adapt to different angles and different shapes of terminal sockets.

[0042] Furthermore, a needle-shaped copper core 21 is provided at the end of the contact 20 away from the pen barrel 12.

[0043] The needle-shaped copper core 21 can be used to test some smaller terminal block sockets.

[0044] Furthermore, the end of the contact 20 near the pen barrel 12 is threaded and is threadedly connected to the pen barrel 12.

[0045] The threaded design of the contact 20 allows for detachable connection of the contact 20 to the pen barrel 12, and also allows for adjustment of the length of the contact 20 by rotating it to accommodate terminal sockets of different depths.

[0046] Furthermore, it also includes an insulating sleeve 50; the insulating sleeve 50 is fitted onto the contact 20.

[0047] Furthermore, the insulating sheath 50 is made of rubber.

[0048] When putting the toolbox away after finishing the work, you can use an insulating sleeve 50 to cover the contact 20 of the shorting pen 10 to prevent it from being damaged by a collision.

[0049] Furthermore, the end of the contact 20 away from the pen barrel 12 is provided with a plurality of protrusions 22.

[0050] By setting the protrusion 22, the friction between the contact 20 and the terminal socket can be increased, making the shorting pen inserted more tightly and preventing it from falling out. The protrusion is about 0.2 mm and is made of the same material as the contact 20.

[0051] Furthermore, it also includes a second insulating cover 60; the second insulating cover 60 is slidably sleeved on the pen barrel 12 and is used to cover the CT terminal block.

[0052] Specifically, the second insulating cover 60 can be made of insulating rubber film material with a diameter of about 35mm and is shaped like a horn bowl. When in use, the second insulating cover 60 can be pushed forward along the pen barrel 12 to cover the entire row of CT terminals in the short-circuit area, thus playing a role in isolation and protection.

[0053] Furthermore, a hanging plate 15 is provided on the pole sleeve 11.

[0054] Since the short-circuited terminals are generally the secondary outputs of the CT, there is a risk of high-voltage electric shock. The mounting plate 15 is equipped with hanging holes, which makes it convenient for maintenance personnel to hang warning signs on the shorted terminal blocks. For example, a warning sign marked "High Voltage Danger, Please Keep Your Distance" can be hung here.

[0055] Furthermore, an indicator light 16 is provided on the pole sleeve 11. The indicator light 16 can be an LED light and is equipped with a switch 17. When the indicator light 16 is needed for a reminder, the switch 17 is pressed, and the LED flashes, which can effectively remind the operator of the work area. Especially when working in dimly lit spaces, this flashing LED light can prevent workers from going to the wrong section and make it easier for maintenance personnel to find any CT terminal block short wires that have not been removed.

[0056] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
