Abstract
The utility model discloses a special electroscope for a contact net, which comprises an insulative operating rod, wherein the insulative operating rod is connected with an electroscope rod, and the front end of the electroscope rod is provided with an acoustic-optic alarm; a safety fuse is arranged in the electroscope rod, and a 120KV high voltage current limiter forms a closed path with the acoustic-optic alarm; the lower end of the electroscope rod is designed with a jack in which a grounding wire is inserted, and the grounding wire is connected with a magnetic electrode which can be attached to a steel rail; the insulative operating rod is composed of a knobbed telescopic rod. The utility model can correctly judge whether the contact net is electrified or not, and can precisely set a starting alarming voltage and correctly discriminate whether the contact net is electrified or has inducting electricity so as to ensure the overhaul of the contact net of an electrified railway.
Description
Technical field
The utility model relates to the special-purpose electroscope of a kind of contact net, is specially adapted to the maintenance of contact nets in electrified railways.
Background technology
The current high voltage electroscope that uses in the maintenance process of contact nets in electrified railways is in use because the false alarm phenomenon often appears in faradic existence.Discover when the reason that causes the electroscope false alarm is the operation of multiple line section V-arrangement skylight and can not have a power failure simultaneously owing to the up-downgoing contact net, the induced electricity that produces owing to the induction of adjacent net-fault on the contact net that causes having had a power failure is very high, sometimes can reach volt more than 10,000, and the galvanoscopic alarm range of using now can not accurately be set, when the alarming value of setting is higher, be easier to the fault that electricity is not reported to the police, when the alarming value of setting is low, be easier to take place the fault of induced electricity false alarm.Experiment finds that factor such as abnormal curved, the ambient humidity of this galvanoscopic alarm voltage and electric field intensity, electric field has much relations, and these factors are difficult to regularly grasp, the therefore very difficult accurate setting of this galvanoscopic alarm voltage.
Summary of the invention
Task of the present utility model is to propose a kind ofly can accurately to set the warning starting potential, and can correctly distinguish electricity or faradic special-purpose electroscope are arranged on the contact net.Task of the present utility model is finished like this, the special-purpose electroscope of contact net, it comprises insulating bar, it is characterized in that: insulating bar connects an electroscope bar, the front end of electroscope bar is equipped with audible-visual annunciator, insurance fuse and 120KV high-voltage and current-limitation device and audible-visual annunciator are housed in the electroscope bar constitute path, design the jack that is inserted with ground wire in electroscope bar lower end, be connected with the magnet electrode that can be adsorbed onto on the rail on the ground wire.Insulating bar is made up of the multi-joint telescoping bar.The utlity model has following effect, overcome the defective that old-fashioned electroscope alarm voltage can not accurately be set, can judge correctly whether contact net is charged, can accurately set the warning starting potential, and can correctly distinguish contact net electricity or induced electricity are arranged, thereby ensured the safety of the upkeep operation of contact nets in electrified railways.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation at Figure 1A place.
Drawing explanation: 1, printing opacity alarm; 2,120KV high-voltage and current-limitation device 3, plug; 4, ground wire; 5, magnet electrode; 6, insulating bar; 7, electroscope bar; 8, insurance fuse.
Embodiment
Describe embodiment in detail in conjunction with above accompanying drawing, electroscope bar 7 of connection on the insulating bar 6, front end at electroscope bar 7 is equipped with audible-visual annunciator 1, insurance fuse 8 and 120KV high-voltage and current-limitation device 2 are put into 7 li on electroscope bar, constitute path with audible-visual annunciator 1 and 120KV high-voltage and current-limitation device 2 by insurance fuse 8, design has jack in electroscope bar 7 lower ends, cooperates with the plug 4 of ground wire, and holding of ground wire 4 is not connected with the magnet electrode 5 that can be adsorbed onto on the rail.Magnet electrode 5 with ground wire 4 during the electrical verification operation is adsorbed on the rail reliably, pull out in the plug reeve jack of electroscope bar 7 with ground wire 4 upper ends, and carry out self check and test, and then all insulating bar 6 location that stretch, earlier electrical verification on the electric position should galvanoscopicly be arranged, prove that this electroscope performance is intact, electrical verification on construction part then.Adopt the high-voltage and current-limitation device directly to measure the voltage of contact net, judge according to the voltage swing of measuring whether contact net has electricity, can accurately set the warning starting potential, thereby whether the difference contact net has, can accurately set the warning starting potential, thereby the difference contact net there are electricity or salty answering.According to be normal charged contact net voltage about 25 kilovolts, whether the induced voltage of power failure contact net judges greater than 14 kilovolts whether contact net charged according to measuring voltage about 10 kilovolts.When measuring voltage is sent sound and light alarm during greater than 14 kilovolts, the indication contact net has electricity, and the indication contact net of not reporting to the police when measuring voltage is lower than 14 kilovolts is not charged.
Claims (2)
1, the special-purpose electroscope of contact net, it comprises insulating bar, it is characterized in that: insulating bar connects an electroscope bar, the front end of electroscope bar is equipped with audible-visual annunciator, insurance fuse and 120KV high-voltage and current-limitation device and audible-visual annunciator are housed in the electroscope bar constitute path, design the jack that is inserted with ground wire in electroscope bar lower end, be connected with the magnet electrode that can be adsorbed onto on the rail on the ground wire.
2, the special-purpose electroscope of contact net according to claim 1, it is characterized in that: insulating bar is made up of the multi-joint telescoping bar.
