Abstract
The utility model provides a high-voltage electroscope packing box. The utility model comprises a box cover, a box body, an electroscope cavity which is arranged at one side of the box body, a cell box and a voltage-boosting box which are arranged at the contiguous position of the other side of the box body. A voltage booster and a connecting rod which is positioned at the upper part of a switch of the voltage booster are arranged in the voltage-boosting box, one end of a connecting rod is fixed on the voltage-boosting box, the other end of the connecting rod is connected with a contact block, and the contact block is corresponding to a testing hole which is arranged at the top part of the voltage-boosting box. When the utility model is used, a contact head of the electroscope needs to be inserted from the testing hole, and the contact block is slightly pressed; thus, the switch of the voltage booster can be closed, and whether the electroscope is in normal working state or not can be tested; thereby, the utility model has the advantages of safe work and convenient carrying.
Description
The utility model relates to a kind of high voltage electroscope packing box, the particularly a kind of packing box that high voltage electroscope can be collected and carried and test.
Existing high voltage electroscope packing box all only has the function that voltage detector is collected and carried.Whether for guaranteeing safety, need detect voltage detector before use can normal operation.Normally adopt the special high-pressure producer or other charged body that carry in addition to detect now.During operation outside, except that carrying the voltage detector box, also need carry a high voltage generators, action and use are all very inconvenient.
The purpose of this utility model is to provide a kind of high voltage electroscope packing box, is provided with checking system in this packing box, can carry out safety detection to voltage detector, carries to reach, purpose easy to use.
Solution of the present utility model is that the voltage detector box comprises lid, box body, it is characterized in that being provided with the voltage detector chamber in box body one side, opposite side is provided with battery case and the box that boosts, the battery case and the adjacent setting of box of boosting, and in battery case, be provided with battery, boost and be provided with booster, connecting rod and contact block in the box, connecting rod one end is fixed on the box that boosts, and be positioned at above the booster switch, the box top is provided with test hole boosting, be provided with contact block corresponding to test hole, this contact block is connected with the connecting rod other end, then is connected by lead between battery and the booster.
Above-mentioned booster comprises coil B, triode BG, resistance R, diode D, K switch, coil B comprises coil ab, cd and ef, power supply is connected with collecting electrode, emitter and the coil ab of triode BG on the one hand by K switch, the base stage that connects resistance R, diode D, triode BG on the other hand by coil cd successively, wherein coil ab and cd are primary winding, and coil ef is a secondary winding.
Advantage of the present utility model is to be provided with in the packing box booster, can produce voltage detector is detected needed high pressure, detects safety, reliable.And voltage detector can be packed in the voltage detector chamber, and is easy to carry.During use, only need the voltage detector contact head is inserted test hole, light crimping contact block, if voltage detector display lamp flash of light and sounding a buzzer shows that then voltage detector is in operative condition, thereby fool proof, convenient.
Accompanying drawing 1 is the utility model front view.
Accompanying drawing 2 is the utility model birds-eye vieies.
Accompanying drawing 3 is the utility model booster circuit schematic diagrams.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
The utility model comprises box body 1, lid 10 etc., is provided with the cavity of shelving voltage detector 11 in box body 1 one sides. opposite side is provided with the battery case 3 and the box 4 that boosts, the battery case 3 and the box 4 adjacent settings of boosting.Be provided with booster 5, connecting rod 9, contact block 8 in the box 4 that boosts, connecting rod 9 one ends are fixed in the box 4 that boosts on the sidewall adjacent with battery case 3, also are provided with the hole of passing through for lead on this sidewall, and this lead is connected battery with booster 5.Another sidewall (corresponding to above-mentioned sidewall) upper end at booster is provided with micro-switch 6, and connecting rod 9 is positioned at the top cover below of the top of switch 6, the box 4 that boosts.Be fixed with contact block 8 at connecting rod 9 other ends, be provided with test hole 7 corresponding to the top cover of contact block 8.In box body 1 and lid 10, all be provided with filling member 2.
During use, open the lid 10, voltage detector 11 is taken out, pull out expansion link, contact head is aimed at test hole 7 insert, contact head is depressed contact block 8 gently, makes connecting rod 9 touch micro-switch 6, switch 6 closures downwards.This moment, power supply Ec was added to the collector and emitter of triode BG by coil a, b, and simultaneously, power supply Ec is through coil c, d, resistance R and diode D are added to triode BG base stage, make the BG conducting, produce induced voltage, after the high pressure winding boosts, obtain high pressure at a, b two ends.When triode BG is full close conducting after, the current change quantity of coil a, b reduces, the feedback quantity of coil c, d reduces, and makes triode BG withdraw from the saturation region and enters the amplification region, this variable quantity transfers BG to after amplifying to end.So go round and begin again, induce high pressure, then can be used for checking voltage detector whether to be in normal working at coil e, f two ends.If the voltage detector light-emitting diode flash, and buzzer phone sounds, and shows that then this voltage detector is in normal working, thereby not only detects safe and reliablely, especially is easy to carry, and uses also very convenient.
