During row, in the north, the icing of roof gradually turns to water to south during operation, and this liquefaction process causes locomotive roof
Decreasing insulating, while the sleet that also has of decreasing insulating may be caused, dense fog and insulator dirt etc., as locomotive fortune
A very important potential safety hazard during.After top insulation punctures, locomotive roof will appear from serious short circuit, and its is short
Road electric current is up to more than 2000A.Thus caused direct result is exactly power network tripping operation, but now driver is not aware that current electric grid
Trip accident is due to that the train or other reasons of this car top insulation hydraulic performance decline or other on-line operations are caused, so
After power supply network power transmission again, rising bow may induce the major accident for burning power network to failure train again.The function of the present apparatus
The roof current conditions of train in running are monitored in real time for above technical problem, when occurring excessively stream, by failure situation
And corresponding Disposal Measures Real-time Feedback is to driver, to prevent second accident, it is to avoid cause bigger social influence and warp
Ji loss.
Current solution is mainly started with terms of control measures and technical measures two, and wherein control measures mainly have：
1st, strengthen the operation of cleaning porcelain vase, in order to reduce top insulation breakdown accident, provide that each locomotive time section will be right
Insulator is cleaned, to reduce the Insulation Problems caused by the dust and greasy dirt on insulator as far as possible.
2nd, the management operated to pantograph is strengthened, for example, requiring that changing end does not change bow during locomotive operation, during avoiding lifting from bending
Arcing may be caused, power network is blown, meanwhile, in order to avoid the excessive wear of same pantograph, provide to change once for two days or so again
Bow.
Above-mentioned control measures can only play prevention effect, if the tripping operation of insulation breakdown power network is there occurs during locomotive operation,
The implementation of control measures can not solve the decision problem of accident, can still cause driver do not know current electric grid trip accident be by
Caused in the train or other reasons of this car top insulation hydraulic performance decline or other on-line operations.
Using traditional top insulation detection means, the device carries out inverse to the 110V direct currents of locomotive itself battery
Become, then boost to 25kV to detect top insulation situation by high-voltage mutual inductor, but the device has the following disadvantages：
1）Existing high-voltage mutual inductor underpower on locomotive, by the high pressure of 110V voltages inversion to 25kV and output one
Fixed electric current needs the presence of certain limitation on the transformer of relatively high power, hardware condition.
2）Traditional roof insulation detection device needs active operation, it is impossible to monitoring in real time, if being insulated after locomotive outbound
Puncture, driver, which is possible to not know, to be needed to carry out Insulation monitoring, still in the presence of the risk of blindness rising bow.
