In the high-voltage electric appliance production's sample, the pattern, the technical paper, the inspection report, the test report, the instruction for use and the production's name brand, often use each kind of specialized term terminology, they express the product structural feature, the technical performance and the use environment.

Understands and has a good command of these noun terminology to be possible to bring many conveniences for the work, At present let's introduction the high-voltage electric appliance equipment terminology.

1.High-voltage switch - - rated voltage 1kV and above，mainly uses in breaking and gathers galvanic circle's electric appliance.

2.High-voltage switch equipment - - high-voltage switch and control, survey, protection, adjusting device, components, the holder and so on. And also the auxiliary, outer covering and support coupling's general name.

3.The indoors high-voltage switch equipment - - don't have windproof, rain, snow, ice, thick frost and so on, is suitable for install in constructs the high-voltage switch equipment which in the place uses.

4.The outdoors high-voltage switch equipment - - can receive chill, the rain, the snow, the contamination, dew, ice and thick frost, is suitable for install in the open-air use high-voltage switch equipment

5.Metal seal switching equipment; The switch cabinet - - besides enters going beyond a line, other earth completely are the metal shell seal's switching equipment.

6.The armor type metal seal switching gear - - main components  (e.g. circuit breaker, mutual inductor, bus bar and so on) install separately, in the earth metal partition board separates into the chamber's metal seal switching gear.

7.The gap or the metal seal switching gear - - is the same with the armor type metal seal switching gear, its' components also load separately with independent separation, but has one or many protection rank nonmetallic partition board.

8.Box-type metal seal switching gear - - except armor type, gap type metal seal switching gear's metal seal switching gear.

9.The gasification type metal seal switching gear - - metal seal switching gear's separates indoor has one of following pressure systems' metal seal switching gear to use for the controlled atmosphere pressure one.
a.Controllable pressure system; b. confining pressure system; c. seal pressure system.

10.The insulation seal switching gear - - except the enters-exports' line, others are all covering by insulate seal switching gear.

11.Combines' electric appliance - -put two kind or more than two kinds high-voltage electric appliances, composes as an organic whole according to the electrical power system main wiring request, but each electric appliance still maintained the original stipulation function the installment.

12.The gas insulation metal seal switching gear - - enclosed type combination electric appliance, at least some parts uses higher than the atmospheric's gas to take the isolation medium's metal seal switching gear.

13.The circuit breaker - - can open-closed, the load bearing, start breaks the movement return route normal current, also to be able in the scheduled time open-closed, the load bearing and opens breaks the stipulation the excess current (including short-circuit current) the switching gear.

14.The sulfur hexafluoride sulfur circuit breaker - - contact open-closed in the sulfur hexafluoride's gas, break the circuit breaker which breaks.

15.The vacuum circuit-breaker - - contact the circuit breaker which in the vacuum open-closed, breaks.

16.Isolator switch - - in the divide position, between the contact conforms to the establish requirements insulation to be away from and the obvious separation symbol; On the closed position, can load bearing the normal return route condition under the electric current and in the scheduled time the exception condition (e.g. short circuit) under current breaker equipment. 

17.The earthing switch - - uses in the return route earth one kind of mechanical type switching arrangement. In the exception condition (for example under the short circuit, may in the scheduled time the load bearing stipulation abnormal current); Under the normal return route condition, does not request the load bearing electric current.

18.The load switch - - can open-closed, the load bearing and the drop-out current in normal return route condition. Also can return route condition in the stipulation unusual (for example short circuit condition), load bearing electric current switching arrangement in stipulation time.
