Problems solved by technology
But the projected thickness in the vertical direction of the both sides of the cabinet door of the above-mentioned existing switchgear is equal to or less than the projected thickness of the part between the two sides on the cabinet door in the vertical direction, so the structural strength of the two sides is still the same. It is relatively weak, which leads to the unsatisfactory explosion-proof effect of the cabinet door of the switchgear, which limits the improvement of the explosion-proof and safety of the switchgear

Embodiment Construction
[0081] The present invention will be further described in detail below in conjunction with the accompanying drawings. Wherein, the descriptive terms such as up, down, left, right, etc. are used for the description, with the purpose of helping readers to understand, but not intended to limit.
[0082] Such as Figure 5 to Figure 13 As shown, an explosion-proof structure of a middle-mounted switchgear includes a cabinet door 10, and one side end of the cabinet door 10 in the width direction is hinged with the cabinet frame 30 through a hinge (not shown in the figure), and the other side The end is connected with the cabinet frame 30 through a lock structure; the door panels at both sides of the cabinet door 10 in the width direction are convexly formed with bosses 11 .
[0083] After the above-mentioned explosion-proof structure is installed, protruding bosses 11 are formed on both sides of the cabinet door 10 in the width direction. In this way, the panel located between the t...

The invention discloses a blast resistant structure of a mid-set switch cubicle. The blast resistant structure comprises a cubicle door, one side end, in the width direction, of the cubicle door is hinged to a cubicle frame through hinges, and the other side end, in the width direction, of the cubicle door is connected with the cubicle frame through a buckle structure. The blast resistant structure is characterized in that the convex columns are formed on the parts, at the two side ends, in the width direction, of the cubicle door, of a door plate in an outward protruding mode. The blast resistant performance of the blast resistant structure is better, and thus higher safety is achieved. The invention further discloses a machining method of the blast resistant structure. The machining method is characterized in that the blast resistant structure is quickly machined and formed with a whole metal plate, and thus the machining production efficiency of the cubicle door can be remarkably improved.
Description
technical field [0001] The invention belongs to the field of electrical switch cabinets, and in particular relates to an explosion-proof structure of a central switch cabinet and a processing method thereof. Background technique [0002] The power system is an electric energy production and consumption system including power generation (power plant), power transmission (transmission and transformation lines), power transformation (substation), power distribution (power distribution station or power distribution room) and power consumption. The switchgear is a kind of electrical equipment that switches, controls and protects the transmission line during the transmission and distribution process of the power system. Center-mounted switchgear (full name is metal armored center-mounted removable switchgear) is one of many types of switchgear, mainly used in the voltage level of 10kV to 35kV. A (handcart type) vacuum circuit breaker is installed inside the central switchgear. T...
