Abstract
The utility model belongs to equipment in the electric power industry, and particularly relates to an interlocking mechanism between a grounding switch and the rear door of a switch cabinet. The interlocking mechanism comprises the rear door (1) of a switch cabinet, wherein a rotatable interlocking device (4) is fixed at the edge of the rear door (1) of a switch cabinet; the interlocking device (4) is connected with the main shaft of the grounding switch; a lock tongue (5) is disposed on the interlocking device (4); a locking device (2) matched with the interlocking device (4) is disposed at the centre of the rear door (1) of a switch cabinet and at the inclined upside of the interlocking device (4); and a lock tongue hole (2-1) is disposed on the locking device (2). The locking device on the rear door of a switch cabinet and the interlocking device enable the rear door of a switch cabinet not to be opened when the grounding switch is off, and only when the grounding switch is on, interlocking is opened, and the rear door of a switch cabinet can be opened, thus avoiding entrance into charged interval by mistake and ensuring the safety of operating personnel.
Description
Technical field
The utility model belongs to power industry and uses equipment, interlocking gear between particularly a kind of earthed switch and switch cubicle back door.
Background technology
In the design of high-tension switch cabinet, the body of switch cubicle is required to have five anti-functions, that is: 1, prevent that on-load from closing a floodgate; 2, prevent to be with earth connection to close a floodgate; 3, prevent mistakenly entering charged chamber; 4, prevent charged hanging earthing conductor; 5, prevent that on-load from connecing disconnecting link.And operation the time is difficult to accomplish to prevent mistakenly entering charged chamber between existing earthed switch and switch cubicle back door, makes troubles to operating personnel.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, and interlocking gear between a kind of simple in structure, safe and reliable earthed switch and switch cubicle back door is provided.
The technical scheme that the utility model technical solution problem adopts is: interlocking gear comprises the switch cubicle back door between earthed switch and switch cubicle back door; Be characterized in fixing rotating interlock in the edge at switch cubicle back door; Interlock connects the earthed switch main shaft; Dead bolt is arranged on interlock, be provided with the locking device that matches with interlock, on locking device, be provided with dead bolt hole at the center at switch cubicle back door, the oblique upper of interlock.
The beneficial effect of the utility model is: at locking device on the switch cubicle back door and interlock the switch cubicle back door can not be opened when earthed switch is opened; When having only earthed switch to close; Chain opening; The switch cubicle back door just can be opened, thereby avoids mistakenly entering charged chamber, guarantees operating personnel's safety.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the front view of interlocking gear structure between earthed switch and switch cubicle back door.
Fig. 2 is that figure cuts open in the office of overlooking of Fig. 1.
Among the figure, 1-switch cubicle back door; The 2-locking device; The 2-1-dead bolt hole; 3-locking device holder; The 4-interlock; The 5-dead bolt; The 6-set bolt.
Embodiment
Embodiment, with reference to accompanying drawing 1,2, interlocking gear is that interlocking gear 4 fixedly is equipped with set bolt 6 in middle part, edge on switch cubicle back door 1 between earthed switch and switch cubicle back door, and interlocking gear 4 is provided with dead bolt 5, and dead bolt 5 connects the main shaft of earthed switches.In the middle part at switch cubicle back door, the oblique upper of interlocking gear 4 is with the fixing locking device holder 3 of set bolt 6, fixing locking device 2 on the locking device holder 3 is provided with dead bolt hole 2-1 on locking device 2.Dead bolt 5 on the interlocking gear 4 is when earthed switch separates, and the rotating band moving lock tongue 5 of main shaft is locked among the dead bolt hole 2-1 on the locking device 2, and the switch cubicle back door can not be opened.
