Distribution box is switchgear, measuring instrument, protection electrical equipment and auxiliary equipment are assembled in sealing or the semiclosed metal cabinet and constitute power distribution equipment by the electrical wiring requirement, is extensively applied to each power station, distribution substation, electric substation, industrial and mining enterprises, construction place etc.
Because the distribution box long term exposure is in extraneous natural environment, the difference of its residing environment causes its sealing property to reduce, usually can be because of entering such as rainwater cause electric leakage, electric shock accidents takes place.In large-scale construction site, the distribution box of use is many, when leaking electricity, being difficult for realizing that which distribution box goes wrong during electric shock accidents, can not in time fault be got rid of, and be prone to cause consequences such as equipment scaling loss, fire, serious even consequence that casualties takes place.
The utility model content
The purpose of the utility model is to the deficiency of prior art a kind of warning distribution box to be provided, and can carry out leakage-current alarm to the electric leakage distribution box, warnings of seeking help, so as accurately, timely location accident distribution box, for discharge fault fast provides foundation.
The technical scheme that the utility model adopted:
A kind of warning distribution box comprises switchgear, measuring instrument, protection electrical equipment, it is characterized in that being provided with warning circuit, and warning circuit is electrically connected with the city through Switching Power Supply, and Switching Power Supply can carry out civil power to be warning circuit conveying power supply after the pressure regulation; Electric leakage indicating module in the warning circuit be connected in parallel with emergency stop switch again after relay is connected, the leakage switch of wherein leak electricity indicating module and distribution box is connected in series, when electric leakage takes place the circuit of distribution box; The leakage switch action; Outage, leakage switch trigger the electric leakage indicating module, make the electric leakage indicating module that electric leakage signal is outputed to relay; The actuating of relay makes the normally opened contact of relay closed; Two normally opened contacts of relay are connected with acousto-optic buzzer, codified wireless signal transmitting module respectively; When the normally opened contact of relay is closed; Connect the control circuit of acousto-optic buzzer, codified wireless signal transmitting module; Buzzer is sounded the alarm and warn light, the codified wireless signal transmitting module is sent alarm signal; The receiver that is arranged on command centre receives the leakage-current alarm buzzer of connecting corresponding numbering distribution box behind the signal, and leakage-current alarm is accomplished, and command centre handles the electric leakage accident according to warning distribution box position arrangement electrician; Two normal battles of emergency stop switch are connected with acousto-optic buzzer, codified wireless signal transmitting module respectively; When the distribution box of certain position need be sought help; Press emergency stop switch; Connect the control circuit of acousto-optic buzzer, codified wireless signal transmitting module, buzzer is sounded the alarm and warn light, the codified wireless signal transmitting module is sent alarm signal, the receiver that is arranged on command centre receives the alarm buzzer of seeking help of connecting corresponding numbering distribution box behind the signal; Seeking help reports to the police accomplishes, and command centre handles various accidents according to warning distribution box position arrangement related personnel.
The utility model is simple in structure; Through control acousto-optic buzzer, codified wireless signal transmitting module; Can to the electric leakage distribution box carry out leakage-current alarm, the warning of seeking help; So as accurately, timely location accident distribution box, for discharging fault fast foundation is provided, guaranteed the fail safe of job site temporary electricity effectively.
