Problems solved by technology

It should be pointed out that when the switchgear is used in special occasions such as underground substations in mines, the depth of the cabinet is too large, which makes transportation and installation difficult, and makes the span of the underground substation too large to increase costs. Occasions cannot even be arranged opposite to each other, so the miniaturization of electrical switches is the development trend of global switching appliances

no. 1 Embodiment

[0030] As shown in the figure, the integrated dual power supply switch of the present invention includes a handcart 100 that can move forward and backward, and the handcart includes a vertical carrier 110 that is fixedly connected or integrally formed, and is fixedly installed on the said handcart. The above-mentioned three groups of poles 120 on the vertical carrier board, each group of poles includes three horizontally extending horizontally spaced and embedded poles with contacts formed on the head ends, and the three groups of solid-sealed The poles are respectively used to communicate with the electrical equipment and the two power sources. At the same time, an actuator, such as a circuit breaker, is provided on the handcart to connect the corresponding solid-sealed pole of the electrical equipment with the solid-sealed pole of the two power supplies.

[0031] It also includes an integrated insulated connection conversion mechanism 130 corresponding to the three groups of...

no. 2 Embodiment

[0038] The intensive dual-power switch of the present invention includes a driven pallet 2 that can be lifted vertically, a handcart 210 that can move back and forth relative to the pallet, a horizontal carrier 220 fixedly connected to the pallet, and a vertical The three groups of poles 230 fixedly arranged on the horizontal support plate, each group of poles include three poles extending along the vertical direction and arranged at intervals from left to right, the three groups of solid-sealed poles The poles are respectively used for the incoming poles of the electrical equipment and the two power sources.

[0039] Among them, it also includes an integrated insulated wiring conversion mechanism corresponding to the three groups of solid-sealed poles, which includes a block-shaped body, a contact box formed on the opposite side of the body and the solid-sealed poles, and formed on the main body The connecting terminals corresponding to the wiring side and connected to the co...

Abstract

The invention discloses an intensive dual-power-supply changeover switch, which comprises a handcart, multiple groups of solid-sealed poles arranged on the handcart, and an integrated insulation wiring changeover mechanism, wherein the integrated insulation wiring changeover mechanism comprises a block-shaped body, contact boxes formed at corresponding sides of the body and the solid-sealed poles,wiring terminals which are formed on the body and a wiring side and are connected with the contact boxes by means of copper bars; the wiring terminals, the contact boxes and the copper bars are integrated through casting by adopting an insulating material; the wiring terminals can be divided into three groups arranged at intervals from top to bottom, the groups are arranged on the same horizontalplane at intervals from top to bottom, that is, the wiring terminals are of a positive mounting structure, and the wiring terminals corresponding to each group of solid-sealed poles are arranged on the same horizontal plane and are distributed at intervals. According to the intensive dual-power-supply changeover switch, the wiring terminals corresponding to electricity utilization equipment are arranged at the top part and can be electrically connected by means of the copper bars in a cabinet body directly, and the two groups of wiring terminals below are connected with cables entering the cabinet from the bottom part, thus the overall width is reduced while the positive-mounting using habit is satisfied.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to an intensive dual power supply switch. Background technique [0002] The three-phase poles of traditional circuit breakers are usually installed in a frontal way, because it is convenient for wiring and also beautiful. However, the disadvantage of this installation method is that it will increase the width of the switchgear and increase the occupied area. At the same time, because the handcart of the circuit breaker moves forward and backward in the cabinet, the depth of the cabinet is also deepened accordingly. Taking KYN28 metal-enclosed switchgear as an example, the circuit breaker sub-car needs to move back and forth 200 mm from the test position to the working position, so the depth of the KYN28 cabinet reaches about 1500 mm. The depth of the cabinet is an important indicator that affects the area occupied by the switchgear in the substation, especially when the...
