Abstract

The utility model discloses an outdoor high-voltage isolating switch which mainly comprises a pedestal, an insulating column, a wire holder, a left contact head and a right contact head, wherein the insulating column is fixed on the pedestal, the conducting wire holder and the left and the right contact heads are arranged on the insulating column, the left and the right contact heads are respectively connected with the end parts of the conducting tube of the insulating column, the contacts of the contact heads are approximately U-shaped, the contacts are connected to the contact holders through bolts, and the contact holders are sleeved at the end parts of the conducting tube. The contacts are reliably connected with the contact heads through the mechanical tension thereof, thereby reducing the work load of the maintainer and the loss of electric energy and improving the equipment operating rate and the power supply reliability.

Description

A kind of outdoor high-voltage isolating switch
Technical field
The utility model relates to the outdoor high-voltage technical field of electrical equipment, especially relates to a kind of outdoor high-voltage isolating switch.
Background technology
Outdoor high-voltage isolating switch because of have dependable performance, simple in structure, install that maintenance is easy, applied widely, versatility, series are strong etc., and advantage is extensive use of in transformer station, be used under immunization with gD DNA vaccine, carrying out folding for high-tension line, and, also can be used for branch, close little electric capacity or inductive current being carried out electrical isolation by electric equipment such as maintenance high voltage bus, circuit breaker and charged high-tension line.Isolating switch is made up of base, insulation column, junction block, left contact, right contact, ground connection fixed contact, ground connection plug-in strip and binding clip, in the structural representation of contact assembly shown in Figure 1, two fingertips 3 are separately positioned on fingertip seat 2 both sides, spring 5 is connected between two fingertips by the pin 4 at two ends, be provided with limiting plate 6 between two fingertips, the fingertip cover for seat is located at contact tube 1 end.The pulling force tension fingertip that isolating switch relies on the spring between the left contact fingertip reliably is connected with right contact, but because outdoor high-voltage isolating switch operates in outdoor, service conditions is very abominable, be in operation and lack maintenance, reasons such as service life is long, spring tension reduces, seriously corroded, in left contact fingertip and the junction loose contact of right contact, when load was heavy, the electric current that passes through was bigger, isolating switch can produce very high temperature in this junction, serious meeting burns out equipment, influences the normal operation of electrical network, has reduced the reliability of power supply.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of simple in structure, easy to operate outdoor high-voltage isolating switch.
For achieving the above object, the utility model adopts following technical scheme:
Described outdoor high-voltage isolating switch, it mainly includes base, insulation column, junction block, left contact, right contact, insulation column is fixed on the base, and band conductive connection seat, left and right contact contact tube are housed on the insulation column, and left and right contact is connected to its contact tube end; Described contact fingertip is approximate " U " shape, and fingertip is connected on the fingertip seat by bolt, and the fingertip cover for seat is located at the contact tube end.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This outdoor high-voltage isolating switch, it is simple in structure, cost of manufacture is low, easy and simple to handle, rely on the mechanical tension of fingertip self reliably to be connected, solved because of spring corrosion, pulling force reduce the contact clamping force that causes and reduced the problem of contact heating with contact, reduce maintainer's the workload and the loss of electric energy, improved equipment operation rate and power supply reliability.
Description of drawings
Fig. 1 is the structural representation of existing contact assembly;
Fig. 2 is the structural representation of fingertip of the present utility model;
Fig. 3 is the structural representation of contact assembly of the present utility model;
Among the figure: the 1-contact tube; 2-fingertip seat; The 3-fingertip; The 4-pin; The 5-spring; The 6-limiting plate; The 7-fingertip; The 8-bolt.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Fig. 2,3, this outdoor high-voltage isolating switch, it mainly includes base, insulation column, junction block, left contact, right contact, insulation column is fixed on the base, band conductive connection seat, left and right contact contact tube are housed on the insulation column, and left and right contact is connected to its contact tube end; Described contact fingertip 7 is approximate " U " shape, and fingertip 7 is connected on the fingertip seat 2 by bolt 8, and fingertip seat 2 is set in contact tube 1 end.
