Abstract
The utility model provides a street lamp controller with earth leakage protection, belongs to lighting equipment technical field, includes controller that links to each other with the power and the lighting module who links to each other with the controller, and the key lies in: still include the voltage sample module, electric leakage alarm module and the pilot lamp that link to each other with the controller, the input of voltage sample module links to each other with the lamp pole of street lamp. The utility model discloses an useful technological effect is: have the alarm, instruct lamp indicating, close multiple processing modes such as lighting module, ensure the personal security.
Description
Technical field
The utility model belongs to fixture technical field, is related to one kind and carries the earth leakage protective controller of street lamp.
Background technology
The lamp stand of street lamp is the good conductor of electric conductivity, equipment in running, due to reasons such as component ageing, damages
Failure of insulation can be led to, will appear from leaky, make equipment become an electrical body, people can occur personal injury thing after touching
Therefore.In China, street lamp device adopts ground protection mostly, but it cannot be guaranteed that electrical leakage voltage is down to the safety electricity of national regulation
Pressure（42V）Below.
Earth leakage protective of the prior art using current mode earth leakage protective and is arranged on cable, not only inconvenient, dimension
Repair also very inconvenient, because sunkening cord many, humid environment in supply line underground, polluted by greasy dirt, dust, in these adverse circumstances
In, the leakage current of cable is often greater than 30mA at ordinary times, if loading onto current mode leakage protector in the line, can often trip,
Electric power system cannot normal work.If current value selection is excessive, do not have protective effect.
It is therefore desirable to develop a with earth leakage protective controller for road lamp, except having controller for road lamp function
Outward, also there is leakage-current alarm, take the function of power down process if necessary.
Content of the invention
Problem to be solved in the utility model is to provide one kind to carry earth leakage protective controller for road lamp, by arranging voltage
Sampling module, leakage-current alarm module and indicator lamp, reach detection and voltage the early warning simultaneously of comparing street lamp post.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is：One kind carries earth leakage protective street lamp
Controller, including the controller being connected with power supply and the lighting module being connected with controller, be it is critical only that：Also include and controller
Connected voltage sample module, leakage-current alarm module and indicator lamp, the input of described voltage sample module and the lamp stand of street lamp
It is connected.
Further, it is additionally provided with PWM adjustment module between controller and lighting module.
Further, it is provided with voltage comparison module in controller and voltage sample intermodule.
Further, described leakage-current alarm module is buzzer.
Advantageous Effects of the present utility model are：There is alarm, indicator lamp instruction, close multiple disposal such as lighting module
Mode is it is ensured that personal security.
Below in conjunction with the accompanying drawings the utility model is described in detail.
Brief description
Fig. 1 is the structural representation that the utility model carries earth leakage protective controller for road lamp.
In the accompanying drawings：1 is controller, and 2 is lighting module, and 3 is voltage sample module, and 4 is leakage-current alarm module, and 5 refer to
Show lamp, 6 is PWM adjustment module, and 7 is voltage comparison module.
Specific embodiment
Referring to accompanying drawing, the utility model provides one kind and carries earth leakage protective controller for road lamp, is connected including with power supply
Controller 1 and the lighting module 2 being connected with controller 1, it is critical only that：Also include the voltage sample mould being connected with controller 1
Block 3, leakage-current alarm module 4 and indicator lamp 5, the described input of voltage sample module 3 is connected with the lamp stand of street lamp.
It is additionally provided with PWM adjustment module 6 between controller 1 and lighting module 2, to adjust the voltage x current of lighting module 2.?
It is provided with voltage comparison module 7 between controller 1 and voltage sample module 3.Leakage-current alarm module 4 is buzzer.
The utility model is in the specific implementation：Two magnitudes of voltage, i.e. reference voltage V 1 He is set in voltage comparison module 7
The numerical value of V2, wherein V2 is more than the numerical value of V1.Voltage sample module 3 gathers the voltage of street lamp post, and by the voltage collecting
Data sends voltage comparison module 7 to.The voltage detecting is compared with voltage comparison module 7 internal reference voltage, if ratio
The reference voltage V 1 setting is low, although having leaked electricity now, leakage-current alarm module 4 refuses alarm；If than the benchmark electricity setting
V1 is high for pressure, lower than V2 it indicates that lamp 5 lights, prompting must not touch lamp stand；If higher than the reference voltage V 2 setting, control
Device 1, cut-out under the control of controller 1 compares the power supply of bright module 2.
