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 conversion switch, which includes a handcart, multiple groups of solid-sealed poles arranged on the handcart, and an integrated insulated wiring conversion mechanism, which includes a block body formed on the The contact box on the corresponding side of the main body and the solid-sealed pole is formed on the main body and the wiring side and is respectively connected to the contact box through the copper bar. The terminal, the contact box and the copper bar are made of insulating material Pouring as one. The connecting terminals are three groups arranged at intervals up and down, and each group is arranged on the same horizontal plane. And interval distribution. The connecting terminals corresponding to the electrical equipment are set on the top, which can be directly connected electrically through the copper bars in the cabinet, while the two sets of connecting terminals at the bottom are connected with the cables entering from the bottom. the overall width.

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...
