Abstract
The invention discloses an alarming device for falsely opening an electrified space cabinet door, comprising a power source and a stroke switch arranged on a cabinet door. A normally-opened contact of the stroke switch is connected with a voice alarming device, the other side of the stroke switch is connected in series with a contact of an electroscope, and the power source is arranged between the voice alarming device and the contact of the electroscope. The invention judges whether the cabinet is electrified by utilizing the contact of the electroscope, the normally-opened contact of the stroke switch is closed when the cabinet door is opened when equipment is electrified, a circuit is switched on, and an alarm sends a voice signal to alert a client that the equipment is electrified so as to stop operation. No any prompting is changed to voice alarming, thereby the reliability of protecting people who violate regulations to falsely enter the electrified space is greatly increased, the safety and the efficiency of construction are increased and the security is greatly improved.
Description
Technical field
The invention belongs to electrical equipment technical field, particularly a kind of alarming device for falsely opening electrified space cabinet door.
Background technology
At present, electric power energy has spread to the every aspect of people's lives as a kind of necessity for life.Simultaneously, electric energy is again a kind of high-risk energy, and operational management must possess professional skill.In order to prevent personal electric shock casualty accident, the power equipment live part adopts the metal cabinet to isolate, seal in a large number, prevents that people and other objects from entering, and causes the injury of the person or equipment.Electricity does not have any feature as a kind of high-risk energy, cannot see and can't hear, and when charging equipment cabinet door is opened, does not possess the personnel of professional knowledge, under the situation of no any caution, has Danger Electric shock risk at any time.Especially high-low-voltage electrical equipment cabinet along with economic development, extensively divides on both sides of the street, populous zone.Even if specialty operation and maintainer also need must not arbitrarily open or enter charged cabinet in strict accordance with carrying out after the relevant regulations outage when operational inspection, overhaul of the equipments.The a lot of high-low pressure person electric shock casualty accidents that before taken place, outstanding problem concentrates on: mistakenly entering charged chamber.
1, operating personnel in time do not latch, and the layabout opens cabinet door error shock carrying device.
2, the outdoor cabinet door door lock corrosion of exposing to the sun and rain, ineffective.
3, the high-voltage operation personnel do not operate by the rules requirement, and mistake is opened charging equipment cabinet door.
Summary of the invention
The invention provides a kind of charging equipment cabinet door of can working as and miss when opening, can in time carry out the device of audio alert prompting.For the litigant provides last one barrier, inform the litigant with speech form, equipment is charged, must shut-down operation prevent electric shock accidents.
A kind of alarming device for falsely opening electrified space cabinet door, comprise power supply and be arranged on cabinet door upper stroke switch, the normally opened contact of described travel switch connects phonetic alarm device, the opposite side of described travel switch is connected with the electroscope contact, and described power supply is arranged between phonetic alarm device and the electroscope contact.
Whether the present invention utilizes galvanoscopic contact to judge in the cabinet charged, when the charged situation lower cabinet door of equipment is opened, and travel switch normally opened contact closure, circuit turn-on, alarm send voice signal as " Danger! Keep Away ", warning litigant equipment has electricity, shut-down operation.Change audio alert into by original no any prompting, increased the reliability that mistakenly entering charged chamber violating the regulations is protected greatly, increased the safety and the efficient of construction, security improves greatly.Appearance of the present invention will remind personnel's equipment charged, avoid taking place the accident of human electric shock, improve power equipment, the security of people's lives and properties.The present invention is simple in structure, and easy purchase of the material of choosing and price are cheap, generally promote and verification experimental verification than being easier to.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1: a kind of alarming device for falsely opening electrified space cabinet door, comprise power supply and be arranged on cabinet door upper stroke switch, the normally opened contact of described travel switch connects phonetic alarm device, the opposite side of described travel switch is connected with the electroscope contact, and described power supply is arranged between phonetic alarm device and the electroscope contact.
Whether the present invention utilizes galvanoscopic contact to judge in the cabinet charged, when the charged situation lower cabinet door of equipment is opened, and travel switch normally opened contact closure, circuit turn-on, alarm send voice signal as " Danger! Keep Away ", warning litigant equipment has electricity, shut-down operation.Change audio alert into by original no any prompting, increased the reliability that mistakenly entering charged chamber violating the regulations is protected greatly, increased the safety and the efficient of construction, security improves greatly.Appearance of the present invention will remind personnel's equipment charged, avoid taking place the accident of human electric shock, improve power equipment, the security of people's lives and properties.The present invention is simple in structure, and easy purchase of the material of choosing and price are cheap, generally promote and verification experimental verification than being easier to.
