Utility model content
The purpose of this utility model is that in order to solve, existing temporary protection device manufacturing cost is high, body structure is complicated, volume is comparatively large, use procedure wiring is loaded down with trivial details, and the problem of inconvenient operation, and proposes a kind of portable temporary protection device.
A kind of portable temporary protection device, its composition comprises: the shell body of box, stating shell body front surface is control panel, described control panel upper left quarter sets gradually action indicator and involution button, the lower left quarter of described control panel sets gradually time delay and drops into pressing plate and instantaneous input pressing plate, arranges one group of connection jaws on the right side of described control panel;
Described shell body front panel arranges four operation window, the hinged emergency exit body in described shell body rear portion, installs digital time relay, three digital current relays and three auxiliary relays in described shell body; Auxiliary relay described in one of them connects described time delay respectively and drops into pressing plate, described instantaneous input pressing plate and second described auxiliary relay, described time delay drops into pressing plate and connects described three digital current relays more respectively, described instantaneous input pressing plate connects described digital time relay again, and second described auxiliary relay distinguishes connecting moves indicator light and described connection jaws again;
Described digital time relay is corresponding with operation window described in one of them to be installed, and three described digital electric current relaies are corresponding with other three described operation window respectively to be installed; Described shell body side has handle, and described shell body bottom surface has one group of feet.
The beneficial effects of the utility model are:
First the utility model is studied the design of the schematic diagram of portable temporary protection device, the selecting of relay element, the problem such as the design of device inner bin and the layout of element, then studies its practical fail safe and details.Design the temporary protection device of the body structure that can adapt to on-the-spot actual needs, and original temporary protection device schematic diagram is improved, redesigned a set of casing, both met relaying configuration scheme, also meet on-the-spot portable easy-to-use demand.
Original 53cm × 40cm × 25cm specification tapers in the little portable box of 28cm × 26cm × 12cm by temporary protection device of the present utility model, has volume little, lightweight, is easy to carry, not fragile, is convenient to the advantage of laying and transporting; In addition; temporary protection utensil of the present utility model has installs advantage easy to adjust; installment work only need use test wire grafting; Set-value adjustment only needs button to complete; current ration regulates step-length to reach 0.1A; time Set-value adjustment step-length is 0.01s, and without the need to carrying out secondary load coupling, has the advantage that wiring is simple, signal is distinct.The prototype part used recycles after transformer station escalates into Microcomputer Protection to eliminate the old device got off, and manufacturing cost is reduced about 80%, and the subsequent parts needed for it and maintenance part supplement fully.
