Description
Technical field
The utility model relates to a kind of protective device, and particularly a kind of electrical network with dust reduction capability is with screen protection protecting cover.
Background technology
Along with expanding economy, people are also increasing to the demand of electrical network, so staff wants regularly to overhaul electrical network; Along with relaying protection integration degree increases; the same screen of transformer station is provided with the protective device of many circuits cashier's office in a shop jointly; when maintainer tests to protective device; careless slightly; very likely be strayed into another circuit; cause the generation of relay protection of power system " by mistake touch, tuning error, mis-wired " accident, and traditional maintenance mode can make circuit long term exposure in atmosphere, causes impurity, dust enters in screen cabinet.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of modern design, safety durable and the electrical network with dust reduction capability with screen protection protecting cover.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of electrical network is with shielding dustproof protective cover, and comprise cabinet and cover sheet, described cabinet is provided with cover sheet, described cover sheet inside is provided with gauze layer, and described cover sheet is provided with observation window, and described observation window is provided with handle.
Described cover sheet is provided with air-vent, and air-vent one has nine.
Described cover sheet side is provided with lock nose, and lock nose is provided with lockhole.
Positive beneficial effect of the present utility model is:
1, the utility model is provided with observation window on cover sheet; observation window is provided with handle; staff is when carrying out service work; whole screen cabinet need not be opened; only the observation window of correspondence need be opened, avoid the generation that circuit too much causes " by mistake touch, tuning error, mis-wired " accident.
2, the utility model is provided with air-vent on cover sheet, ensure that in screen cabinet smoothness of ventilating; Cover sheet inside is provided with gauze layer, avoids the impurity such as dust, the grains of sand and enter in screen cabinet; Staff only needs regularly to change gauze layer and clean, and solves the problem of circuit dust difficulty cleaning in screen cabinet, easy to use, cost-saving.
3, the utility model is provided with lock nose and lockhole at cover sheet side, when not using screen cabinet so at ordinary times, cashier's office in a shop can lock protect at screen, avoids other people malicious damage screen cabinet internal wiring, ensure that the safe operation of electrical network.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
See Fig. 1, a kind of electrical network, with shielding dustproof protective cover, comprises cabinet 1 and cover sheet 2, cabinet 1 is provided with cover sheet 2, cover sheet 2 inside is provided with gauze layer 3, cover sheet 2 is provided with observation window 4, observation window 4 is provided with handle 5; Cover sheet 2 is provided with air-vent 6, and air-vent 6 one has nine; Cover sheet 2 side is provided with lock nose 7, lock nose 7 is provided with lockhole 8.
