Abstract
The utility model discloses a cabinet door interlocking device of a switch cabinet in an electric power distribution system. The utility model is characterized in that a pushing plate (2) is welded on a right door (1) of the switch cabinet, an interlocking bending plate (5) is welded on a left door (6) of the switch cabinet, an interlocking rod (4) passes through a middle side plate (3), and a spring (7) is arranged on the interlocking rod (4). The cabinet door interlocking device of the switch cabinet has the advantages of simple structure, safety, reliability and cost saving, and conforms to the requirements of preferential adoption of mechanical interlocking of the switch cabinet.
Description
Technical field
The utility model relates to a kind of switch cubicle in the electrical power distribution system, and is special relevant with the interlock of indoor metal armoring door of switch cabinet.
Background technology
In the electric power power transmission and transformation system of rated voltage 3.6～40.5kV, three-phase alternating current 50Hz, a kind of indoor metal armoring formula switch cubicle commonly used, such door of switch cabinet often needs interlocking, and access door electromagnetic lock commonly used is realized electrical interlock at present.When not meeting switch cubicle like this and preferentially adopt the requirement of mechanical interlocking and electrical interlock often inefficacy to be arranged.
The utility model content
The utility model is to design a kind of simple in structure, safe and reliable switch cabinet door interlock.
The technical solution adopted in the utility model is: a kind of switch cabinet door interlock, be characterised in that, and on the right door of switch cubicle, be welded with push pedal, on the switch cubicle left-hand door, be welded with the interlocking bent plate, be installed with blocking lever in the middle side plate, blocking lever is provided with spring.
The switch cabinet door interlock that the utility model provides, the blocking lever that is promoted to move in side plate by push pedal enters the interlocking bent plate, when the right door of switch cubicle is opened, from the interlocking bent plate, skid off under the effect of blocking lever at spring, realize mechanical interlocking thereby make between switch cubicle left-hand door and the right door of switch cubicle.
Simple in structure, safe and reliable, save cost, meet the requirement that switch cubicle preferentially adopts mechanical interlocking.
Description of drawings
Accompanying drawing is the structural representation of the utility model switch cabinet door interlock embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, the right door 2 of switch cubicle, push pedal 3, side plate 4, blocking lever 5, interlocking bent plate 6, switch cubicle left-hand door 7, spring
As shown in the figure, the utility model switch cabinet door interlock is to be welded with push pedal 2 on the right door 1 of switch cubicle, is welded with interlocking bent plate 5 on switch cubicle left-hand door 6, is installed with blocking lever 4 in the middle side plate 3, and blocking lever 4 is provided with spring 7.
Promote to enter the interlocking bent plate 5 of welding on the switch cubicle left-hand door 6 at the blocking lever 4 of 3 li motions of side plate by the push pedal 2 on the right door 1 of switch cubicle, blocking lever 4 skids off from interlocking bent plate 5 under the effect of spring 7 when the right door 1 of switch cubicle is opened, and realizes mechanical interlocking thereby make between right door 1 of switch cubicle and the switch cubicle left-hand door 6.
The switch cabinet door interlock that the utility model provides is simple in structure, safe and reliable, save cost, meet the requirement that switch cubicle preferentially adopts mechanical interlocking.
