Abstract
The connection terminal rank includes connection seat. There are connection slots on the connection seat, and there are connecting compression tablets. Characters are that there are longitudinal notches on two ends of connection seat. Two ends of insulated compression bar are inserted to the longitudinal notches. Compression teeth on the insulated compression bar press the connecting compression tablets. Being installed on two sides of the insulated compression bar, each insulated cover board is installed on the connection seat. Being above the insulated compression bar, the insulated compression plate is installed on the connection seat fixedly. The disclosed connection terminal rank is suitable to process connections of large numbers of signal lines in high voltage in experimental apparatus of national big science engineering EAST.
Description
Technical field
The invention belongs to a kind of a kind of peripheral components that uses in building superconducting tokamak device, specifically is a kind of multipurpose anti high voltage connection terminal row.
Background technology
Country's big science engineering EAST device is the large-scale fusion research experimental provision of a full superconduction.Because of the measurement device requirements of one's work, each subsystem all has large number of signal lines to draw, and the laying of these holding wires generally all needs to connect through transfer.
Commercially available in the market connecting terminal block, of a great variety, generally adopt the engineering plastics material, be applicable to the power-frequency voltage occasion, insulation voltage 600V.
A large amount of high-voltage signal lines are arranged in the EAST experimental provision, and the connection processing of these high-voltage signal lines is a difficult point always.Because matching requirements class of insulation 10kV, common connecting terminal block can't reach requirement, therefore needs the connecting terminal block of a kind of class of insulation of design more than 10kV, the high-voltage signal line is carried out transfer connect.
Summary of the invention
The purpose of this invention is to provide a kind of anti high voltage connection terminal row, the class of insulation can reach withstand voltage technical requirement more than 10kV.
Technical scheme of the present invention is as follows:
Anti high voltage connection terminal row, include junction block, connecting groove is arranged on the junction block, the wiring compressing tablet is arranged on the connecting groove, it is characterized in that there is vertical fluting at described junction block two ends, insert in described vertical fluting at insulation depression bar two ends, the tooth pressure of pressure is arranged on the wiring compressing tablet on the insulation depression bar, insulation depression bar both sides have respectively has an insulation cover plate to be installed on the junction block, and insulation depression bar and insulation cover plate top have insulating press boards to be fixedly mounted on the junction block.
On the described wiring compressing tablet screw is installed, in corresponding described vertical fluting the counterbore that holds screw is arranged.
The present invention is a kind of multiduty anti high voltage connection terminal row, and is simple in structure, easy for installation, class of insulation height.Its advantage is:
(1) easy for installation.Overall dimension is applicable to the occasion that common connecting terminal block is installed.
(2) through-current capability height.Change the electric conducting material cross-sectional area, can reach more than the 100A by electric current.
(3) the upper surface insulation cover plate guarantees safety.
(4) class of insulation is up to more than the 10kV.By increasing the surface creepage distance, the class of insulation can be brought up to higher level.
The invention effect
In the use, the present invention replaces common connecting terminal block position and installs, and through Insulation test, reaches the requirement of withstand voltage of 10kV fully.
The voltage-withstand test experiment:
Test condition:
The adjacent position is withstand voltage: DC.10kV, 1 minute.
The voltage-withstand test result:
Leakage current:＜0.1 μ A.
Insulation resistance:＞100G Ω
This structural member is applied in EAST tokamak device project.
Description of drawings
Fig. 1 is an exploded view of the present invention.
Embodiment
Anti high voltage connection terminal row, include junction block 1, connecting groove 2 is arranged on the junction block 1, wiring compressing tablet 3 is arranged on the connecting groove 2, there is vertical fluting 4 at junction block 1 two ends, and insert in described vertical fluting 4 at insulation depression bar 5 two ends, has the tooth 6 of pressure to be pressed on the wiring compressing tablet 3 on the insulation depression bar 5, insulation depression bar 5 both sides have respectively has an insulation cover plate 7 to be installed on the junction block 1, and insulation depression bar 5 and insulation cover plate 7 tops have insulating press boards 8 to be fixedly mounted on the junction block 1.
On the wiring compressing tablet 3 screw is installed, in corresponding described vertical fluting 4 counterbore that holds screw is arranged.
Each parts of the present invention adopt the special epoxy material of G10 material, improve the withstand voltage level of terminal board; All all polishings of parts wedge angle part prevent the generation of point discharge phenomenon; All parts adopt does not have oil processing; All epoxy parts surfaces apply the insulating varnish coating, and through baking oven baking in 24 hours, remove the moisture in the epoxy material, and effectively prevent material suction in the use, reduce insulation level; Electric conducting material adopts the cathode copper material of pb-sn alloy plating, changes vertically fluting 4 and electric conducting material size, and through-current capability can reach more than the 100A.
Claims (2)
1, withstand voltage connecting terminal block, include junction block, connecting groove is arranged on the junction block, the wiring compressing tablet is arranged on the connecting groove, it is characterized in that there is vertical fluting at described junction block two ends, insert in described vertical fluting at insulation depression bar two ends, the tooth pressure of pressure is arranged on the wiring compressing tablet on the insulation depression bar, insulation depression bar both sides respectively have an insulation cover plate to be installed on the junction block, and insulation depression bar and insulation cover plate top have insulating press boards to be fixedly mounted on the junction block.
