Abstract
The utility model is implemented by the following technical scheme: a door interlocking mechanism and a switch cabinet with the same. The door interlocking mechanism comprises a locking plate with a connecting part connected with a gate of a grounding mechanism and a gap; and a door with a barrier sheet for limiting the locking plate, wherein an opening matched with the gap is formed on the barrier sheet. The door interlocking mechanism disclosed by the utility model has the main advantages that: by the design that the interlocking plate and the door are matched with a slot, a cable cabin door is ensured to be locked at an ungrounded position; and the door interlocking mechanism is simple in structure, simple and convenient to operate, and reliable in protection.
Description
Technical field
The utility model relates to the electric equipment field, particularly a kind of switch cubicle that is used for the gate interlock mechanism of switch cubicle and has it.
Background technology
The switch cubicle of cable machinery is housed in the prior art, has no safeguard procedures at closing time opening.If the operator opens the cable hatch door in the unearthed mistiming of earthed switch, then electric shock accidents takes place in the possibility mistakenly entering charged chamber.
The utility model content
The utility model improves prior art, and a kind of gate interlock mechanism is provided, and mandatoryly prevents that earthed switch is in the hatch door mistake of closing when not closing the position and opens, with the correctness that guarantees operation sequence and operator's personal safety.
The utility model is realized through following technical scheme: a kind of gate interlock mechanism comprises: locking plate, have the connecting portion that is connected with the gate of earthing mechanism, and locking plate has breach; Door has the catch that limits locking plate, forms the opening that cooperates with breach on the catch.
Further, locking plate has broadside and narrow limit, and the width of broadside is wider than narrow limit, and position, narrow limit forms breach, and the width of opening is wider than narrow limit, is narrower than broadside.
Further, locking plate is connected through rivet with gate.
Further, catch is arranged on the groove of door.
Further, catch is arranged in the groove movably.
According to a further aspect in the invention, a kind of switch cubicle, inside holds earthing mechanism, has aforesaid gate interlock mechanism.
Through technique scheme, the major advantage of the utility model is, through locking plate and door cooperate the draw-in groove design, guarantee the locking of cable hatch door at non-earthing position, simple in structure, easy and simple to handle, protective is reliable.
Description of drawings
The accompanying drawing that constitutes the part of the utility model is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the sketch map of locking plate of gate interlock mechanism of an embodiment of the utility model;
The gate interlock mechanism that Fig. 2 shows an embodiment of the utility model is in the sketch map of locking states;
The gate interlock mechanism that Fig. 3 shows an embodiment of the utility model is in the sketch map of unlocking condition; And
Fig. 4 shows the sectional view of gate interlock mechanism of an embodiment of the utility model.
Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The locking plate of gate interlock mechanism of an embodiment of the utility model has been shown among Fig. 1.Width was inconsistent about this locking plate 2 was processed as, and had broadside and narrow limit, just had breach 22 in the position on narrow limit.Locking plate 2 is connected together through screw hole 21 with the gate motion parts of earthing mechanism, and along with the separating brake and the combined floodgate of earthing mechanism, locking plate 2 moves up and down in the groove of cable hatch door.The catch 1 of opening 12 is arranged in the middle of having on the groove of cable hatch door, and opening 12 width between the catch 1 are greater than the width on narrow limit, less than the width of broadside.When the broadside of locking plate 2 and narrow limit move in the groove respectively, realize locking and the function of unblanking.
The sketch map that is in locking states of gate interlock mechanism of an embodiment of the utility model has been shown among Fig. 2.When switch was in the position of ground connection separating brake, locking plate 2 moved to position shown in Figure 2, and the broadside of locking plate moves to the interior catch of groove 1 time, and locking plate is stuck in the groove, can not pull the cable hatch door outward.When being grounded separating brake, the function of locking cable hatch door guarantees the correctness of operation sequence and operator's personal safety.
The gate interlock mechanism that Fig. 3 shows an embodiment of the utility model is in the sketch map of unlocking condition.When switch is in contact of earth, during the position of safety ground, locking plate 2 moves to position shown in Figure 3, and the breach 22 of locking plate 2 moves to the opening 12 times of the catch 1 in the groove, and locking plate does not limit catch 1 and moves, and switch cubicle is a ground state, can draw back the cable hatch door outward.
Fig. 4 shows the sectional view of gate interlock mechanism of an embodiment of the utility model.The relative position relation of locking plate 2 and catch 1 is shown, is illustrated as the situation of broadside under catch 1, this moment, locking plate 2 was blocked by catch 1.Expect that easily when the breach 22 of locking plate moves to catch 1 time, can from opening 12, deviate from, door can smooth opening.
Gate interlock structure according to the utility model has following beneficial effect:
The safeguard function that the utility model is mainly realized is that to prevent that earthed switch from not closing fashionable, and mistake is opened cable hatch door, mistakenly entering charged chamber.After the furnishing door interlock, the ground connection of closing can be opened the cable hatch door; Ground connection separately, interlock locking cable hatch door just can the mandatory operator of preventing be in mistakenly entering charged chamber when cut-offfing the position at earthed switch, with guarantee operation sequence correctly and operator's personal safety.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
