Embodiment 1

[0053] This embodiment provides an interlocking structure of a switch cabinet. Such as Figure 2-5 As shown, the first circuit breaker 1 is installed in the first switch cabinet 10, the second circuit breaker 2 is installed in the second switch cabinet 20, and the first circuit breaker 1 and the second circuit breaker 2 are installed side by side in the horizontal direction.

[0054] The switchgear interlocking structure of this embodiment is suitable for being arranged between the above-mentioned first circuit breaker 1 and the second circuit breaker 2, and specifically includes: The first blocking portion 31 and the second blocking portion 32 at the end; the installation structure is used to install the push rod 3 on the first switch cabinet 10 and the second switch cabinet 20, and enable the push rod 3 to move along the The main body part 30 moves back and forth in the axial direction; the first blocking block 11 is adapted to be fixedly arranged on the first circuit break...

Embodiment 2

[0074] This embodiment provides an interlocking switchgear, including a first switchgear 10 installed with a first circuit breaker 1, and a second switchgear 20 installed with a second circuit breaker 2, between the first switchgear 10 and the second The switch cabinet 20 is installed with the interlocking structure of the switch cabinet as in the first embodiment.

[0075] Since the interlocking switchgear provided by this embodiment is equipped with the above-mentioned interlocking structure, it has all the advantages brought by the installation of the above-mentioned interlocking structure.

Abstract

The invention provides a switchgear interlocking structure and an interlocked switchgear cabinet, wherein the switchgear interlocking structure adapts to be arranged between a first circuit breaker and a second circuit breaker which are installed side by side. The switchgear interlocking structure specifically comprises a top rod, a mounting structure which makes the top rod installed in an axially movable manner on the switchgear cabinet, a first block fixedly arranged on the first circuit breaker, and a second block fixedly arranged on the second circuit breaker. The switchgear interlocking structure has a simple structure and is conveniently installed. When a circuit breaker is switched on, the top rod is pushed by the block arranged on the corresponding circuit breaker and moves to the other switching-on path of the other circuit breaker, thereby automatically blocking the switch-on of the other circuit breaker. The switchgear interlocking structure is safe and reliable, and convenient to use.

Description

technical field [0001] The invention relates to the technical field of an interlocking structure of a switch cabinet and an interlocking switch cabinet, in particular to an interlocking structure of a switch cabinet and an interlocking switch cabinet having the same. Background technique [0002] In the secondary power distribution network, the use of dual power sources (that is, common power and backup power) is becoming more and more widespread. In order to ensure that only one power supply is used to supply power to the load each time, people began to set up an interlock structure inside the switch cabinet. The function of the interlock structure is: when the common power supply supplies power to the load, the interlock structure limits the closing operation of the backup power supply. The backup power supply can only be in the opening state and cannot supply power to the load; when the backup power supply is supplying power to the load, the interlock structure restricts ...
