Problems solved by technology

[0007] However, there are two technical problems in the above-mentioned switchgear. One is that the first latch 8 and the second latch 15 need to pass through the partition 3 to work, so that they will rub against the partition when they work, causing mechanical interference; The second is that there is no limit to the unlocking of the switchgear, and anyone can unlock it at will

Embodiment Construction

[0039] image 3 The switchgear of the present invention is shown, which has a cabinet door and an electronic lock 35 arranged on the cabinet door, which is used to receive the unlocking instruction of the handheld mobile terminal. Only when the unlocking instruction meets the unlocking requirements, can the cabinet door be opened so that the staff can carry out Maintenance, thus preventing other unrelated personnel from opening the switchgear at will.

[0040] After the switchgear is opened, the circuit breaker handcart and metering trolley of the switchgear can be overhauled.

[0041] Figure 4 with Figure 5 It shows an embodiment of a switchgear with an interlocking structure of the present invention, including the same cabinet as the prior art, a partition, and an interlocking structure installed on the partition, separated by the first side of the partition The first space for the metering trolley to enter and exit and the second space for the circuit breaker trolley to ...

Abstract

The invention discloses a switch cabinet with an interlocking structure. The interlocking structure includes: a first rotating rod installed on the first side of the partition; a first contact installed at one end of the first rotating rod for When the metering handcart enters the first space and collides, it moves toward the partition; the contact switch is arranged facing the first contact, and is used to turn on the power when the first contact is sensed to move toward the partition circuit; the first electromagnetic stopper installed on the second side of the partition is used for retraction movement when the contact switch is connected to the power circuit, so that the circuit breaker handcart can enter the second space; installed on the second side of the partition The second rotating rod on both sides; the second contact installed at one end of the second rotating rod is used to move toward the partition when the circuit breaker handcart enters and collides; the second contact arranged at the other end of the second rotating rod The rod switch is used to disconnect the power circuit when the second contact moves toward the partition; the second electromagnetic stopper is installed on the first side of the partition.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a switch cabinet with an interlocking structure which can be unlocked according to user instructions. Background technique [0002] Existing switch cabinets usually have the requirement to ensure the "five defenses" interlocking of the switch cabinet. Chinese invention CN108092173 discloses a switch cabinet in order to realize the characteristics of simple and reliable structure and convenient installation and maintenance. [0003] figure 1 The structure of the switch cabinet is shown, including the incoming line cabinet 1 and the metering cabinet 2. The inner cavity of the incoming line cabinet 1 forms the first accommodation space that can accommodate the entry and exit of the circuit breaker trolley, and the inner cavity of the metering cabinet 2 forms The second accommodating space that can accommodate the metering trolley 11. A partition 3 is provided between the first accommodating spac...
