Abstract
The utility model relates to an equipment for power transmission and distribution field. The utility model provides a be furnished with security alarm device and put cabinet in puts in should and install the ground connection sword in the cabinet, ground connection sword and back door bayonet socket cooperate to be put in, and installs anti - blocking device in the cabinet, establish ties in anti - blocking device and ground connection sword auxiliary contact's the circuit and install alarm device, the power supply voltage of circuit is the alternating current 220V, and put that the cabinet back door is close in the middle of, but do not target in place anti - blocking device thimble and by force the ground connection sword back of closing a floodgate, alarm device triggers the actuation of an alarm on the top. The utility model discloses an add installation alarm device in putting the circuit system of cabinet in, under the circumstances that the anti - blocking device at back door did not put in place totally, sound and light is reported to the police to the back door of reminding the staff to put the cabinet again in will run well, meets accident in order avoiding.
Description
Technical field
This utility model relates to equipment for power transmission and distribution field, is furnished with safety alarm device particularly to a kind of
Middle-placed switch cabinet.
Background technology
The interlocking of central cabinet grounding cutter only has an earthing when of initial, earthing has buckle, uses
In interlocking with the buckle on back door, it is achieved back door and the mechanical chain of earthing.But due to earthing
It is all internal at door with the buckle at back door, so what earthing can not be the most pure and fresh after closing a floodgate observes
The buckle of earthing is either with or without interlocking identical with back door buckle, if Men Wei clasps, people can enter easily
Enter the danger that may have electric shock if in middle-placed switch cabinet.Along with science and technology development, middle-placed switch cabinet of today,
The top of earthing has installed a backlocking device additional, and its effect is only when back door is shut, and
After backlocking device thimble top is put in place, earthing could close a floodgate.But practical situation is but at back door
But shut not in the case of uncertain for backlocking device thimble putting in place, as long as strong by bigger strength
Row closes earthing, and earthing also can close a floodgate, but like this, earthing operation handle may fly
Turning, if reaching human body, being likely to result in serious injury.Moreover, due to misoperation,
Cabinet may be caused serious damage.
Utility model content
The purpose of this utility model is to provide the middle-placed switch cabinet of a kind of high security, and this utility model provides
Techniques below scheme:
A kind of middle-placed switch cabinet being furnished with safety alarm device, is provided with earthing in this middle-placed switch cabinet, described in connect
Ground cutter and back door bayonet socket match, and are provided with backlocking device in middle-placed switch cabinet, described backlocking device and
Be installed in series in the circuit of earthing auxiliary contact alarm device, and the supply voltage of described circuit is for handing over
Stream 220V, when middle-placed switch cabinet back door is shut but backlocking device thimble does not push up and puts in place and by force ground connection
After cutter closes a floodgate, alarm device triggers actuation of an alarm.
As a kind of preferred version of the present utility model, described alarm device is electric bell and/or display lamp.
As another kind of preferred version of the present utility model, if the quantity of described electric bell and display lamp is
Dry, can be installed on inside middle-placed switch cabinet, it is also possible to be installed on outside middle-placed switch cabinet.
As another preferred version of the present utility model, described display lamp is normal bright light or flashing lamp.
As another preferred version of the present utility model, the color of described display lamp is red.
This utility model advantage is:
This utility model installs alarm device, when back door by adding in the Circuits System of middle-placed switch cabinet
In the case of backlocking device puts in place the most completely, send sound and light warning, to remind staff
Again the back door of middle-placed switch cabinet is run well, to avoid occurring surprisingly.
The safety alarm device of this utility model middle-placed switch cabinet includes electric bell and display lamp, electric bell and display lamp
Cooperation make no matter staff hears the tinkle of bells or see light, can put in finding in time
Cabinet back door closes the most safely, reminds staff to re-close the back door of middle-placed switch cabinet.
Accompanying drawing explanation
Fig. 1 is this utility model attachment structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this practicality

Protection domain makes apparent clear and definite defining.
As shown in accompanying drawing 1 this utility model attachment structure schematic diagram, a kind of be furnished with safety alarm device
Middle-placed switch cabinet, is provided with earthing, described earthing and back door bayonet socket and matches in this middle-placed switch cabinet, in put
Cabinet is provided with backlocking device, the circuit of described backlocking device and earthing auxiliary contact is connected
Being provided with alarm device, the supply voltage of described circuit is alternating current 220V, shut when middle-placed switch cabinet back door but
Be backlocking device thimble do not push up put in place and by force earthing close a floodgate after, alarm device trigger report to the police
Action.
Described alarm device is electric bell and/or display lamp.The quantity of described electric bell and display lamp is some
Individual, can be installed on inside middle-placed switch cabinet, it is also possible to be installed on outside middle-placed switch cabinet.
Described display lamp is normal bright light or flashing lamp.The color of described display lamp can be multiple color,
Such as red, yellow or other colors.
The above, detailed description of the invention the most of the present utility model, but protection model of the present utility model
