Description

A large current automatic switch device

technical field

The utility model relates to the technical field of switching devices, in particular to a large current automatic switching device.

Background technique

The battery short-circuit test mainly verifies the safety of the battery. The short-circuit test of the battery requires that the test line has an instantaneous large current passing through, and it is especially required that the control switch can be closed smoothly to prevent the switch from sticking. Although the current control switches on the market have an arc-extinguishing function, it is often difficult to "parry" the high-energy lithium battery cell that passes a large current of more than 1000A in an instant short circuit. Once adhesion occurs, it will instantly cause damage to the entire line or even cause problems such as fire, which is dangerous and threatens the health of the staff.

Contents of the invention

In order to solve the technical problem that the traditional control switch device cannot withstand the large current released by the short-circuit of the high-rate battery and realize the unsafe and unstable remote control operation, the utility model provides a high-current automatic switch device.

A high-current automatic switchgear, comprising a fixed insulating mounting plate, characterized in that a downward pressure cylinder is installed above the fixed insulating mounting plate, and a copper connecting row is installed on the end of the cylinder arm of the downward pressure cylinder; The insulated mounting plate is located below the copper connection bar and is provided with two current-carrying lead wires, the upper ends of the two current-carrying leads are provided with copper lead-in electrodes, and the middle parts of the two current-carry lead wires are equipped with red copper lead-in electrodes. An insulating sliding sleeve, a return spring is connected between the red copper leading pole and the insulating sliding sleeve of the red copper leading pole.

Further, when the cylinder arm of the press-down cylinder is in the retracted state, the distance between the copper connecting row and the copper lead-in pole is 2CM-4CM.

The beneficial effects of the utility model are:

The cylinder arm of the down-pressing cylinder of the utility model is equipped with a red copper connection row, a current-carrying lead wire and a design of the red copper lead-in electrode, and the connection and disconnection of the red copper connection row and the red copper lead-in electrode are realized through the expansion and contraction of the cylinder arm. In the event of adhesion, the entire line is protected from fire and remote control operations can be realized, which is safe and stable.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The components in the figure are marked as follows: 01, down-pressing cylinder; 02, copper connection bar; 03, copper lead pole; 04, return spring; 05, copper lead pole insulation sliding sleeve; 06, current-carrying lead wire; 07, fixed insulation installation plate.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings:

As shown in the figure, a high-current automatic switching device includes a fixed insulating mounting plate 07, a down-pressing cylinder 01 is installed above the fixed insulating mounting plate 07, and a copper connection bar 02 is installed on the cylinder arm of the down-pressing cylinder 01; The plate 07 is located below the copper connection bar 02 and is provided with two current-carrying lead wires 06, the upper ends of the two current-carrying lead wires 06 are provided with a copper lead-in pole 03, and the middle part of the two current-carrying lead wires 06 is equipped with a copper lead-in pole insulation slide A return spring 04 is connected between the sleeve 05, the copper lead pole 03 and the copper lead pole insulating sliding sleeve 05; when the cylinder arm of the downward pressure cylinder 01 is in a retracted state, the distance between the copper connection row 02 and the copper lead pole 03 is 2 cm.

When the utility model is used for a short-circuit test, adjust the down-press cylinder 01 to a suitable air pressure value according to the manufacturing standard, fix the two ends of the battery to the positive and negative sides, press the down-press switch of the down-press cylinder 01, and press down The cylinder 01 is pressed down instantly, driving the copper connection bar 02 to move downward, and connecting the copper bar lead pole 03; the copper connection bar 02 is pressed down instantly because the red copper lead pole 03 has a return spring 04 and the copper lead pole insulating sliding sleeve 05 as a "soft In order to effectively ensure large-area contact, avoid the point contact of traditional switches, and completely avoid the phenomenon of adhesion. After the utility model completes the short-circuit test, press the return switch of the down-press cylinder 01, and the cylinder can instantly disconnect the circuit when it rises. When it bears the large current released by the short-circuit of the high-rate electric core, there will be no adhesion phenomenon, and the entire circuit will be protected. Avoid causing fire and can realize remote control operation, safe and stable.

The utility model is a high-current automatic switch device, which can realize remote control operation during short-circuit test, avoid the phenomenon of adhesion, and prevent fire from threatening the health of workers. It has simple structure and convenient operation, and is suitable for use in the field of switch devices. Promotional use.
