Abstract
The invention provides a ground trial jump device of a residual current operated protective device. The ground trial jump device comprises a trial jump fixed box, a light emitting diode arranged on the trial jump fixed box and a trial jump button. The ground trial jump device is convenient to use, can eliminate potential safety hazard, and improves the detection efficiency.
Description
Technical field
The present invention relates to power domain, be specifically related to RCD trial jump device over the ground.
Background technology
Can RCD trial jump device over the ground be cut off the electricity supply under the situation of power circuit and consumer electric leakage in order to test RCD at once, thereby play the simulation test device of protection power equipment, people and animal.According to the rules; the RCD that is installed in the public change in rural area must be simulated electric leakage trial jump and trial jump over the ground in every month; to verify that can it move reliably under the residual current of setting, installation rate, operational percentage, the serviceability rate of the RCD of installing in the outlet of every 0.4kV circuit of the assurance public substation transformer in rural area reach one of three percentages hundred.The distribution operations staff is in the operation of trial jump over the ground of RCD at present; what use is two kinds in semi-fixed type trial jump device and portable trial jump pen; have following defective: the trial jump line is not completely fixed over the ground; the easy oxidation of trial jump line and fractureing; trial jump line apparatus position is unreasonable, operates behind the power distribution cabinet, must be with the instrument of ascending a height; more time-consuming, and in operating process, also exist potential safety hazard.
Summary of the invention
Technical matters to be solved by this invention is to provide RCD trial jump device over the ground, and is easy to use, can eliminate safe hidden trouble, and improves detection efficiency.
For solving above-mentioned existing technical matters, the present invention adopts following scheme: RCD is the trial jump device over the ground, comprises the trial jump fixed case, is located at light emitting diode and trial jump button on the trial jump fixed case.
As preferably, described light emitting diode is connected by the P.e.c. that is provided with the trial jump button.
As preferably, described trial jump fixed case is provided with connection terminal, is provided with fuse between described connection terminal and the P.e.c..
As preferably, be provided with ground wire in the described trial jump fixed case, be provided with current-limiting resistance and trial jump resistance between described P.e.c. and the ground wire.Ground wire is fixed, and has eliminated potential safety hazard.
Beneficial effect:
The present invention adopts technique scheme that RCD trial jump device over the ground is provided, and is easy to use, eliminated potential safety hazard, improved detection efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an inner structure synoptic diagram of the present invention.
Embodiment
To shown in Figure 2, RCD is the trial jump device over the ground, comprises trial jump fixed case 1, is located at light emitting diode 2 and trial jump button 3 on the trial jump fixed case 1 as Fig. 1.Described light emitting diode 2 is connected by the P.e.c. 4 that is provided with trial jump button 3.Described trial jump fixed case 1 is provided with connection terminal 5, is provided with fuse 6 between described connection terminal 5 and the P.e.c. 4.Be provided with ground wire 7 in the described trial jump fixed case 1, be provided with current-limiting resistance 8 and trial jump resistance 9 between described P.e.c. 4 and the ground wire 7.
During use, directly trial jump fixed case 1 is fixed on the cabinet, needs only one during operation by trial jump button 3, convenient and efficient.Operation before button trial jump, the cabinet, change installation site are installed on the trial jump device in the plastic box, are fixed in 1.8 meters of electric pole distance to the ground again, remove ladder or climbers during trial jump from, improve safety factor.Solved the defect problem that exists, brought considerable economic, shortened RCD trial jump running time over the ground, can save time every year 374.4 hours according to statistics, year obtains about 9253.5 yuan of economic benefit altogether.Improve the production run work efficiency greatly, improved the serviceability rate of local power-supply unit better, simultaneously by the improvement of device, the safety coefficient when having improved operations staff's trial jump operation.
