Abstract
The invention relates to a combined electrical appliance. The combined electrical appliance consists of a double-vacuum bubble immobilized pole high-voltage load switch unit, a fuse box, an operating mechanism and a novel cabinet body. Compared with the prior art, the combined electrical appliance has the following advantages that: 1, the epoxy resin immobilization and connection of the high-voltage load switch unit and the fuse box is realized; 2, the horizontal layout of the high-voltage load switch unit and a fuse under the condition of not changing the width of a high-voltage load switch is realized; 3, the tripping state of the fuse is very easy to observe intuitively and obviously through a cabinet door observation window, and the influences of troubles and reliable factors caused by performing secondary simulation are avoided; and 4, a tripping mode is that a tripping semiaxle in the operating mechanism is directly pushed by adopting a pull rod, the design is simple and the operation is reliable.

6The high voltage load switch of insulation has been the general common recognitions of people; In high voltage switchgear power transmission and distribution field, high voltage load switch and switchgear thereof are used for the turnover line unit in power transmission and distribution field, and generally, high voltage load switch+fuse combined electric apparatus unit is selected in the tranformer protection unit.
I have applied for patent of invention at the combined high-voltage on-load switch and the high voltage switchgear thereof of company's research and development in January, 2008, in order to satisfy the supporting demand of electricity market, my company has researched and developed supporting with it high voltage load switch+fuse combined electric apparatus unit again, is called for short combined electrical apparatus.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, volume is less, the insulating protection ability is strong, the dropout mode is simple and reliable, is convenient to solve switchgear of the prior art and uses not environmental protection, dangerous, problem such as easy care not.
Technical scheme of the present invention is achieved in that sealing gasket that fuse box and two vacuum bubbles pole unit by using one particular manufacturing craft pressure injections form has played good sealing effectiveness to being connected between the two, has solved because of existing the gap to cause creepage hidden danger.
Fuse is placed the fuse casing, solve the phase insulation problem, the fuse casing installs the clear glass protective cover of flame-retardant materials additional, is convenient to observe the state of fuse, and has increased the fail safe to plant maintenance and maintainer.
When fuse is threaded off in the described fuse box, the dropout pull bar in the knocking gear, the dropout pull bar backs down dropout semiaxis in the mechanism and carries out separating brake, simplicity of design, operation is reliable.
In the described combined electrical apparatus switchgear, the cabinet door is provided with fuse trip status observation window, realized being easy to observe the trip status of fuse by cabinet door observation window (10), obviously directly perceived, remove from and carry out the trouble that the secondary simulation causes and the influence of unreliable factor.
In the described combined electrical apparatus switchgear, also be provided with the electrical verification passage on the cabinet door, specialize in the electricity consumption department and safeguard and maintainer's electrical verification usefulness, guaranteed safety of operators again.
The invention has the beneficial effects as follows:
Combined electrical product of the present invention are simple in structure, volume is little, environmental protection, insulating protection ability are strong; Realized supporting use with me the combined high-voltage on-load switch and the high voltage switchgear thereof of company's research and development, satisfy supporting requirement with the electric power system switching devices, and combined electrical apparatus is not affected with condition variations such as airborne humidity, dust and insect, eliminated the potential safety hazard of combined electrical apparatus phase fault, the reliability height.
