Description
Technical field
The utility model relates to the wet Withstand test device of a kind of electrical equipment.
Background technology
The development of electrical equipment product or the change of external insulation structure all require drench with rain withstand voltage test examination of external insulation, and seldom there is regular calandria salt fog test equipment in general manufacturing enterprise; Also exist equipment configuration complicated even have, volume is bigger, inconvenient installation; Generally need the examination of long-range fortune test product to the other places; The defective manufacturer that retracts again readjusts product structure, and transportation is extremely inconvenient so repeatedly, influences the completion of research and development progress and task.
The utility model content
Provide the wet Withstand test device of a kind of electric insulation simple in structure, that be convenient to operate the order of the utility model.
To achieve these goals; Adopt following technical scheme, a kind of electric insulation Withstand test device that wets, it is characterized in that: said device is made up of electric support equipment that links to each other with test product and salt fog test device; Wherein the salt fog test device comprises shower nozzle that connects through water pipe and the bracing frame that is used for fixing shower nozzle; Wherein shower nozzle comprises valve body with water inlet and water delivering orifice and the spool that is arranged in the valve cavity, and the runner that said spool is identical by two, intersection links to each other is formed, and the rear end face of two runners is cut flat; The water delivering orifice of valve body is provided with the bellmouth of two positioned opposite; The valve body middle part has the annular boss spacing to the runner rear end face, and under water impact, spool can rotate freely in valve body vertically.
In order to increase inflow, the inboard of said two runners all has opening.
In order to improve the runner rotating speed, the angle between said two runners is an acute angle, and the edge adjacent with the valve cavity inwall is the inclined-plane of distortion on said two runners.
Be installed into wetting system for ease, the outer wall at said valve body water inlet place is provided with external thread, and the front end face of runner is cut flat.
Move for ease, enlarge usable range, said electric support equipment, salt fog test device and test product all are arranged on the mobile platform.
The utility model is simple in structure, and is easy to use, and shower nozzle can change the water smoke that the wet withstand voltage examination of drenching with rain of electric product requires from the common water column that water inlet gets into into; Shower nozzle itself is simple in structure, and is easy to use flexible, can be to distance, angle, the adjustment highly arbitrarily of spraying; Though indoors or the open air all can make an experiment; Overcome the restriction of such test on the test place, made the wet withstand voltage test of insulation convenient and easy, greatly improved the efficient that research and development of products and contract task are paid.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Extremely shown in Figure 5 like Fig. 1; A kind of electric insulation Withstand test device that wets is made up of electric support equipment that links to each other with test product 31 and salt fog test device, and wherein the salt fog test device comprises shower nozzle 2 that connects through water pipe 4 and the bracing frame 5 that is used for fixing shower nozzle; Wherein shower nozzle comprises valve body 22 and spool; All adopt bronze material antirust and that hardness is suitable to make, spool cuts out two runners 21 that fuse for using copper rod, and the inscribe gradient is to increase work torsion on the runner.Two runner arranged crosswise; The runner edge becomes the inclined-plane of distortion, and two runners have opening 23 in an adjacent side respectively, to improve water yield trafficability characteristic; Show the annular boss 24 that is provided with the axially-movable of restriction runner in the valve body internal cavity; Former and later two end faces of runner are cut flat, and rear end face and boss join, and it is in order not influence other equipment of installation that front end face is cut flat.Having the gap between spool and the valve body makes it can in valve body, freely rotate at the hydraulic action bottom spool.
Valve body top is circular, and its outside surface is provided with external thread, makes the rubber water pipe be difficult for landing; Adorn water pressure gauge for other again or encrypt lid and allow some leeway, the middle part is cubic platform, tool using during convenient stressed installation; The lower inside cross section be two relative fan-shaped, fan-shaped central authorities are water delivering orifice.
Shower nozzle can convert common water column from the beginning to and meet the state of drenching with rain that electrical test requires, i.e. all water outlets all are interrupted water droplets in any moment.The hub angle of spool matches with the valve body bellmouth under hydraulic action and to form the shape of drenching with rain, and the rotating speed of spool runner is influenced by hydraulic pressure and runner inclined-plane jointly, and the formation water outlet pressure, the water outlet pressure encirclement volume of confirming to drench with rain.
During use, move or pressure-resistant equipment is moved to the open air, carry out being electrically connected between voltage regulator controllers, step-up transformer and the test product at experiment hall; With band tubing shower nozzle is connected with running water pipe, receives the pouring state, the adjustment water swivel according to shower nozzle state and product; Boost to the magnitude of voltage that product has wet withstand voltage examination with pressure regulator rotation then, keep (being generally one minute) after the stipulated time, fall voltage to zero; The switch of turning off the tap, this device work finishes.
