When carrying out operation maintenance to the transformer substation, need use safety tool, for example: the common characteristic of the tools is that a hand-held part is wrapped with an insulating layer, a set of the tools is prepared in each substation room and is placed at a designated position according to 5S management regulations, and the following problems exist in the field implementation process: 1. in the actual use process, the situation of insulating layer damage is inevitable, the detection of the tool insulation by workers is only simple from the aspect of appearance, and the safety needs to be further improved; 2. the tools are easy to accumulate in the tool box at will after use and are not placed at the designated positions, the fool-proof effect cannot be achieved, the 5S management regulation of the transformer substation cannot be met, vicious circle is very easy to get into, the situation that the tools are lost occurs, and the working efficiency is affected.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a transformer substation's instrument detection case for solve insulating instrument placement effect not good and detect incomplete problem.

The technical scheme of the utility model:

the utility model provides a transformer substation's instrument detection case, including box and case lid, be equipped with the first draw-in groove corresponding with each instrument insulated handle of transformer substation in the box, be equipped with the second draw-in groove corresponding with first draw-in groove on the case lid, all be equipped with the first metal shrapnel of multiunit in each first draw-in groove, all be equipped with multiunit second metal shrapnel in each second draw-in groove, be equipped with the busbar that exposes the metal end corresponding with the instrument on one side of the box, each first metal shrapnel in the first draw-in groove is established ties rather than each second metal shrapnel in the corresponding second draw-in groove, still include a plurality ofly and each first corresponding boost circuit of draw-in groove and insulation measurement circuit, first metal shrapnel and busbar are put through respectively at the boost circuit both ends, insulation measurement circuit puts through second metal shrapnel.

The booster circuit comprises two NPN triodes, two resistors, a power supply, a transformer and a switch which are connected to form the booster circuit, and two ends of the high-voltage end of the transformer are respectively communicated with the first metal elastic sheet and the conductive bar.

The insulation measuring circuit comprises an NPN triode, a PNP triode, a capacitor, a loudspeaker and a power supply which form a detection insulation detection circuit.

Compared with the prior art, the beneficial effects of the utility model are that: each first draw-in groove and second draw-in groove are corresponding with each instrument in the detection case, must place the instrument in each corresponding first draw-in groove after using up the instrument, and each first draw-in groove is corresponding with each instrument shape, can play good fool-proof effect, lets in high voltage to instrument both ends through boost circuit in addition after, detection circuitry detects insulating layer surface insulation effect, detects its insulating effect.
