Abstract
The utility model relates to a line parameter test anti -induction electric installation, its structure does, installation switch and switch in the safety cover, switch and switch are established ties, and earthing terminal, switch one end interconnecting link end are connected to switch one end. When checking the circuit phase place, can be in a looks switch and switch and close the position, the position is divided to double -phase being in in addition. When the experimental wiring of change, can close three -phase switch and switch, with circuit ground connection, prevent that the influence electricity from hurting sb. 's feelings. With three -phase switch and switch disconnection when the test.
Description
Technical field
This utility model belongs to electrical test technical field, particularly relates to a kind of line parameter circuit value test anti-induced electrical device, is particularly well-suited to 220kV and 66kV line parameter circuit value testing ground.
Background technology
For satisfied society power demands, newly-built transformer station and newly-increased circuit are more and more, and the measurement circuit parameter experiment frequency also gets more and more.Every newly-built and transformation circuit need to carry out nuclear phase, and tests the parameters such as actual resistance, electric capacity, inductance, for scheduling and protection seting offer data.For meeting user power utilization reliability, during measurement circuit parameter, adjacent lines or do not have a power failure with tower circuit.Therefore, measurement circuit faradism is relatively big, easily with equipment, human body is being become injury when test.
Utility model content
This utility model is for above-mentioned problems of the prior art, it is provided that a kind of line parameter circuit value test anti-induced electrical device, solve measurement circuit parameter because of induced voltage hurt sb.'s feelings, the problem of burning apparatus.
The utility model proposes following technical scheme:
Line parameter circuit value test anti-induced electrical device, installs disconnecting link and switch, disconnecting link and switch series connection in protective cover, disconnecting link one end connects earth terminal, switch one end connecting line terminal.
Described disconnecting link and switch are three.
Three described moving contact of disconnecting link one end connect three-phase short circuit earth lead, static contact one end connecting valve.
Described disconnecting link and Switch Three-Phase split are arranged.
Described disconnecting link and switch are arranged on insulation board.
This utility model has the advantage that
1,6 are reached due to line parameter circuit value test event, need to frequently change wiring and change test apparatus, use this device, can eliminate because same tower or proximity band electric line are excessive to measurement circuit faradism by line-to-ground during change wiring, cause the injury of the person and equipment, thus avoid faradic injury, improve safety coefficient, and convenient operation, improve work efficiency.
2, it is mounted with switch due to this device, first closes a switch when closing a floodgate and close disconnecting link afterwards, separately time, first divide switch-dividing after disconnecting link, faradism arcing can be avoided.
3, the split of this device three-phase is arranged, and meets one phase hovering, the requirement of other two phase ground during line parameter circuit value nuclear phase.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
1, earth lead, 2, disconnecting link, 3, switch, 4, protective cover, 5, test connection.
Detailed description of the invention
Embodiment
As shown in Figure 1; insulant is used to be fabricated to protective cover 4; three disconnecting links 2 and three switches 3 are installed in protective cover 4; three disconnecting links and three switches are arranged on insulation board, and three disconnecting links and three switches are connected respectively, and moving contact of disconnecting link one end connects three-phase short circuit earth lead 1; static contact one end connecting valve; the switch other end connects three test connections 5, test connection connecting test circuit, forms three-phase split grounding device.
This utility model connects grounding device from line test end, side, effectively avoids faradism directly to hurt sb.'s feelings.When checking line Phases, a phase switch and disconnecting link can be in conjunction position, the most biphase be in a point position.When changing test connection, threephase switch and disconnecting link can be closed, by line-to-ground, prevent faradism from hurting sb.'s feelings.When test by three-phase disconnecting link and switching off.
Above with respect to specific descriptions of the present utility model, it is merely to illustrate this utility model and is not limited to the technical scheme described by this utility model embodiment.It will be understood by those within the art that, still this utility model can be modified or equivalent, to reach identical technique effect.Needs are used, all in protection domain of the present utility model as long as meeting.
