Abstract
The utility model discloses a kind of low-pressure electric cabinet electrocution-proof alarming device, including control system and and with control system and the audible alarm system that connects, wherein control system includes regulator cubicle enter line side 220V power supplys and dynamic circuit connector type relay, and normally closed limit switch is concatenated in the 220V wire loops of the dynamic circuit connector type relay；Audible alarm system includes voltage-stabilized power supply and the voice guard concatenated with voltage-stabilized power supply.When regulator cubicle is powered, that is, when having 220V and above power supply in regulator cubicle, open regulator cubicle cabinet door, normally closed limit switch closure, the adhesive due to powered of dynamic circuit connector type relay coil, control voice guard alarm, and when not charged in cabinet, even if opening regulator cubicle cabinet door, voice guard will not also alarm, maintainer can be so set quickly and easily to judge whether regulator cubicle is powered, so as to avoid the generation of electric shock accidents.
Description
Technical field
A kind of warning device is the utility model is related to, specifically a kind of low-pressure electric cabinet electrocution-proof alarming device.
Background technology
At present, conventional front and rear enabling low-pressure electric cabinet does not have powered warning facility, and when opening, regulator cubicle progress soot blowing is clear
Sweep, element fastening or be easy to that electric shock accidents occurs when changing other upkeep operations such as element；Particularly in maintenance process, stop
Electricity is not in place or leakage has a power failure, is easier to allow maintainer to be mistakenly considered in cabinet to have had a power failure and directly opened cabinet in the case of wrong power failure
Maintenance, causes electric shock accidents frequently to occur.
Utility model content
The purpose of this utility model is to provide a kind of low-pressure electric cabinet electrocution-proof alarming device, electric shock accidents when preventing from overhauling
Generation, improve maintainer work security.
To reach above-mentioned purpose, the utility model uses following technical scheme：A kind of low-pressure electric cabinet shockproof alarm dress
Put, including control system and and include regulator cubicle enter line side with control system and the audible alarm system that connects, wherein control system
220V power supplys and dynamic circuit connector type relay, the dynamic circuit connector type relay concatenate normally closed limit switch；Audible alarm system includes voltage stabilizing electricity
Source and the voice guard concatenated with voltage-stabilized power supply.
Above-mentioned voltage-stabilized power supply selects 220V/≤36V voltage-stabilized power supplies in principle, the preferred 220V/5V's of the utility model
Voltage-stabilized power supply, in the case where ensureing to be supplied to the enough voltage of voice guard, make whole warning device safer.
The utility model has the advantages that compared to prior art：
The utility model adds a set of powered audible alarm that opens the door on the basis of existing front and rear enabling low-pressure electric cabinet
System, delicate structure, automated system operation, when opening band electric cabinet door, voice guard can send alarm signal immediately, warning
This cabinet of operating personnel is powered, so as to prevent the generation of electric shock accidents, has ensured personal security.
Brief description of the drawings
Fig. 1 is the electrical schematic diagram of the utility model low-pressure electric cabinet electrocution-proof alarming device.
Reference：1st, dynamic circuit connector type relay；2nd, normally closed limit switch；3rd, voice guard；4th, voltage-stabilized power supply；K1 distinguishes
Represent dynamic circuit connector type relay and its contact.
Embodiment
In order to more fully understand the utility model, it is described further with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of low-pressure electric cabinet electrocution-proof alarming device, including control system and and with control system and connecing
Audible alarm system, wherein control system includes regulator cubicle enter line side 220V power supplys and dynamic circuit connector type relay 1, the dynamic circuit connector type after
Electrical equipment 1 concatenates normally closed limit switch 2；Audible alarm system includes 220V/5V voltage-stabilized power supplies 4 and concatenated with the voltage-stabilized power supply 4
Voice guard 3.
The course of work of above-mentioned electrocution-proof alarming device is as follows：The 220V power supplys are derived from regulator cubicle enter line side, voltage stabilizing electricity
Source 4 is arranged on the bottom of regulator cubicle, and dynamic circuit connector type relay 1 and voice guard 3 are arranged in Electric Appliance Cabinet on guide rail, normally closed spacing
Switch 2 is arranged on electric cabinet door edge；When regulator cubicle is powered, that is, when having 220V and above power supply in regulator cubicle, electricity is opened
Gas holder cabinet door, normally closed limit switch 2 are closed, the coil adhesive due to powered of dynamic circuit connector type relay 1, and control voice guard 3 is reported
It is alert, and when not charged in cabinet, even if opening regulator cubicle cabinet door, voice guard 3 will not also alarm, and can so make maintenance people
Member quickly and easily judges whether regulator cubicle is powered, so as to avoid the generation of electric shock accidents.
