Abstract

The utility model relates to a circuit detection device, in particular to a detection device for a circuit breaker. The detection device consists of a cross beam and a 'pi'-shaped frame formed by two stand columns fixed at the two ends of the cross beam, wherein two arc-shaped contact fingers are oppositely installed on the two stand columns; and a binding post used for connecting a detection line is electrically connected with the arc-shaped contact finger arranged on one stand column at one side, and a bolt matched with an insulation operating rod is fixedly arranged at the lower end of the stand column at one side. The detection device of the circuit breaker has the characteristics that the structure is simple, and the operation and use are convenient.

Description

The isolating switch pick-up unit

Technical field

The utility model relates to circuit checker, particularly the isolating switch pick-up unit.

Background technology

According to People's Republic of China's electric device commissioning test standard and the Q/GDW168-2008 of State Grid Corporation of China " power transmission and transformation equipment state overhauling testing regulations " regulation, to carry out periodic test to transformer station's inner breaker, because the structure of the isolating switch of voltage levels all is the T-shape structure, the terrain clearance of isolating switch is generally more than 7.20 meters, must carry out wiring at the centre at isolating switch top and two ends during test and come acquired signal.At present carry out periodicity when detecting, all adopt large-scale crane, high-altitude operation vehicle or aerial work platform, the testing staff is delivered to the isolating switch place, carry out the line detection at isolating switch to voltage levels.On the one hand because the early stage transformer station that builds does not all have access path, so just causing large-scale crane or high-altitude operation vehicle can't enter the scene detects, on the other hand, though there is access path in the transformer station that the later stage builds, make the big machinery equipment can enter the scene of detection, but because the restriction of electric power supply reliability, the user requires quite high to power supply reliability, the maintenance of transformer station in the past all is whole stoppages in transit, part interval and circuit now only allow to stop transport when being necessary, detect when on-the-spot when big machinery equipment enters like this, be difficult to when mechanized equipment goes out arm to guarantee and the safe distance of charging equipment, make and detect test and be difficult to finish.So just must be undertaken by high-altitude operation vehicle or aerial work platform, thereby make the required manpower and materials of work increase greatly, but also having increased the security risk of staff's work high above the ground and finishing smoothly of testing, serious threat is to the safe and stable operation of electrical network.

Summary of the invention

The purpose of this utility model is to overcome the existing defective that isolating switch exists that detects, and provides a kind of main equipment that need not to enter the scene of detection, and isolating switch pick-up unit easy to detect, that efficient is high.

For achieving the above object, the technical solution of the utility model is: a kind of isolating switch pick-up unit, it is characterized in that the isolating switch pick-up unit is by crossbeam be fixed on " door " shape framework that two columns at crossbeam two ends form and form, two arc fingertips are installed on two columns relatively, being used for the binding post of joint detection line is electrically connected with arc fingertip on the heel post wherein, the lower end of a heel post is installed with the bolt that matches with insulating bar therein.

Above-mentioned crossbeam is made up of the crossbeam II that is fixed on the crossbeam I on the heel post and be fixed on the opposite side column, and the removable mutual socket of crossbeam I and crossbeam II is equipped with back-moving spring between crossbeam I and crossbeam II.

Above-mentioned back-moving spring is extension spring.

The utlity model has simple in structure, use convenience operation.Because the utility model is made as " door " shape framework, and a column lower end at " door " shape framework is installed with the bolt that matches with insulating bar, when detecting isolating switch, only need this device is linked to each other with insulating bar, just this device can be installed in easily the relevant position of the isolating switch that needs detection by insulating bar, simultaneously, because the removable crossbeam in the elastic reaction of two arc fingertips and " door " shape framework and be installed in the effect of the interior back-moving spring of crossbeam can guarantee that fingertip is electrically connected with the effective of isolating switch.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment

As shown in Figure 1, the isolating switch pick-up unit is made up of crossbeam and " door " shape framework that two columns that are fixed on the crossbeam two ends form, the upper end of the column 5 in left side is fixed with crossbeam I 1, the upper end of the column 8 on right side is fixed with crossbeam II 9, two arc fingertips 4 and is installed in relatively on above-mentioned two columns by fixedly connected hoop 3.Be fixed with the binding post 7 that is used for the joint detection line on the column on right side, binding post is electrically connected with arc fingertip on this column, in the lower end of right side column, is installed with the bolt 6 that matches with insulating bar.For enlarging this device size accommodation, with crossbeam I and the removable mutual socket of crossbeam II, between crossbeam I and crossbeam II, back-moving spring 2 is installed, back-moving spring can adopt extension spring.

The insulating bar of during use appliance maintenance being used links to each other with the bolt 6 of this device, and the detection line that detects usefulness is fixedly mounted on the binding post 7, by insulating bar this device is placed on the isolating switch that needs to detect, and just can finish the detection task easily.
