Abstract
The utility model discloses a rainproof cover for a manually-operated operation mechanism of an outdoor disconnector. The rainproof cover includes a nylon-made umbrella-shaped cover body formed by half-bodies at the two sides, wherein the half-bodies are separated at the middle of the umbrella-shaped cover body. Each of the half-bodies at the two sides is provided with a half-piece hoop at the top end. Connection faces of the half-bodies at the two sides are provided correspondingly with bosses and grooves, which are embedded with each other. The half-piece hoops of the half-bodies at the two sides are fastened through bolts so that a tubular body is formed. The rainproof cover for the manually-operated operation mechanism of the outdoor disconnector reduces the DC grounding rate of the manually-operated operation mechanism of the outdoor disconnector greatly and provides guarantee for all-weather operation of a device and ensures safe and stable operation of a power grid under an environment of severe weather.
Description
Technical field
The utility model relates to outdoor disconnector manual-operating mechanism rain cover.
Background technology
Current most transformer station is all integrated automation converting station, more or less all occurs DC earthing phenomenon.Why there will be this phenomenon? find by analysis it is mainly the DC earthing that 110kV and following outdoor disconnector cause, 110kV and following integrated automation converting station all will be got contact from the auxiliary switch of outdoor disconnector and reflect isolating switch position, locking and secondary voltage switching (secondary voltage of double-bus automatically switches) etc., and its outer cover is irony cylindrical shape.Because isolating switch is for a long time under outdoor harsh climate condition, long-time running, power failure chance is few, outer cover is the bad seal approach of taking again, auxiliary switch body directly contacts with atmosphere, during rainy weather, because rainwater infilters in operating mechanism, makes DC system grounding or secondary voltage ground short circuit.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of outdoor disconnector manual-operating mechanism rain cover, prevents that rainwater from infiltering in operating mechanism, makes DC system grounding or secondary voltage ground short circuit.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of outdoor disconnector manual-operating mechanism rain cover, comprise nylon umbrella shape cover body, described umbrella shape cover body is combined by middle separated both sides Semi separation, Semi separation top, both sides is equipped with half sheet anchor ear, the joint face correspondence of described both sides Semi separation is provided with boss and groove is chimeric, and half sheet anchor ear of described both sides Semi separation forms cylindrical body by bolted.
Preferably, described cylindrical body inwall is provided with seal groove, the interior chimeric sealing ring that has of described seal groove.
Preferably, described boss and groove are strip structure.
Preferably, the Semi separation joint face of described both sides is provided with rubber strip, and the rubber strip on the Semi separation joint face of both sides coordinates by inclined-plane.
The utility model adopts the beneficial effect of technique scheme to be: (1) reduces outdoor disconnector manual-operating mechanism DC earthing rate greatly, for equipment round-the-clock running provides guarantee, has guaranteed electrical network safe and stable operation in bad weather conditions.Meanwhile, reduced substation operation personnel and repaiied examination personnel due to the manpower and materials that the appearance of fault consumes on site fault clearing, guaranteed the safe and stable operation of power equipment and reduce production costs to make certain contribution.(2) alleviate the problem of operating mechanism and five anti-padlock corrosions, increased the reliability of equipment, reduced operation expense.(3) allow unwatched monitor staff promptly and accurately understand the running status of isolating switch and significant to guaranteeing the normal operation of direct current system, double measurement equipment, relaying protection, automatics, the safe operation of power equipment and electrical network has been played to important function.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
The whole vertical view of Fig. 1 rain cover;
Fig. 2 rain cover left and right two parts separate vertical view;
Fig. 3 rain cover unitary side view;
Fig. 4 rain cover left and right two parts separate end view;
Fig. 5 is rubber strip fit structure schematic diagram on the Semi separation joint face of both sides.
Embodiment
Fig. 1 to Fig. 5 shows the concrete structure of the utility model outdoor disconnector manual-operating mechanism rain cover, it comprises umbrella shape cover body 2, by nylon material, made, described umbrella shape cover body 2 is combined by middle separated both sides Semi separation, Semi separation top, both sides is equipped with half sheet anchor ear, the joint face correspondence of described both sides Semi separation is provided with boss 3 and groove 4 is chimeric, and during installation, boss 3 and groove 4 agree with mutually, prevents that rainwater from infiltrating.Half sheet anchor ear of described both sides Semi separation forms cylindrical body 1 by bolted.Half sheet anchor ear is provided with four screws 5, during use, with four pieces of bolts, cylindrical body 1 is held tightly and is fixed on isolating switch manual-operating mechanism.Described cylindrical body inwall is provided with seal groove, and the interior chimeric sealing ring that has of described seal groove, to prevent that rainwater from infiltrating.Described boss and groove are strip structure.The Semi separation joint face of described both sides is provided with rubber strip 6, and the rubber strip on the Semi separation joint face of both sides coordinates by inclined-plane 7, and the inclined-plane of rubber strip coordinates can prevent that rainwater from infiltrating.Boss 3 and groove 4 be chimeric has facilitated installation, also belong to the form of hard sealing simultaneously, and rubber strip inclined-plane 7 coordinates for soft seal, adds the sealing of cylindrical body 1 inner seal ring, and triple seal structure like this can be stopped rainwater infiltration completely.
The utility model has been filled up the blank of the rainproof instrument of outdoor disconnector manual-operating mechanism, is to preventing the improvement of outdoor operating mechanism ground connection and corrosion method.By use of the present utility model, solved (1) isolator operating mechanism for a long time under outdoor harsh climate condition, during rainy weather, because rainwater infilters in operating mechanism, make the problem of DC system grounding or secondary voltage ground short circuit; (2) problem of operating mechanism and five anti-padlock corrosions.
