Abstract

The utility model discloses a hard bus isolating protector which improves the insulating performance of buses. The utility model is composed of a thick wall heat shrinkability tubular body and a Hough clamping sheet, wherein, the Hough clamping sheet is provided with fastening joint teeth, the thick wall heat shrinkable tubular body is used as an insulating protective layer for the flat areas and the twisting positions of the buses, and the Hough clamping sheet is used as an insulating protective body for the connection positions and the fixed points of the buses. Just being assembled on hard buses, the utility model can cover the buses together with screw bolts and screw nuts, and thereby, the purpose of safe isolation is reached. The utility model is a safety device for ensuring personal safety and fully preventing snake, mice, and other animals from touching electrodes. Situations of power distribution and load can be observed from temperature-indicating chromatic film points so that the effects of local corona discharge generated by dust and dirt which are accumulated in electrostatic induction are prevented.

Description

Hard bus isolating protector

The utility model relates to installs the hard bus insulation protective that bus is used in a kind of power distribution equipment.

At present, when the switchboard (case, cabinet) of power distribution device is installed, all hard bus mounting process standard or standard have been worked out.But in these technological documents, the insulation protection of hard bus is not all stipulated, expose outside so the hard bus that we install at present is still.Because bus is exposed, bring Danger Electric shock risk just for detection maintenance mans author; Perhaps run into animals such as snake, mouse enter run into three-phase bus in the cabinet after, instantaneous short circuit takes place, cause unnecessary accident and economic loss.In the hard bus technology chapters and sections of the I of International Electrotechnical Commission, E, C standard, the specification requirement of isolated bus technology is arranged.Part is introduced and is had on the model machine with the composite high-molecular material coating after baking becomes solid-state insulation protection layer process.But this technology, complicated operation, appearance owes attractive in appearance after the moulding.Meet international standards so actively seek the measure of simple possible, the Push Technology progress, improve the quality of products, strive for enlarging foreign trade market, positive effect is arranged.

The purpose of this utility model provides a kind of hard bus insulation protective.It can improve the insulation property of bus; ensure the safety that detects maintenance personal's person and stop the equipment breakdown that the animal's electric shock utmost points such as snake, mouse cause; can in time find overloading fault on the loop from the change color of temperature indicating look film on the insulating protective layer again; facility is made the maintenance scheme, and has the electrostatic induction of preventing to gather the effect that dust and dirt produces local corona discharge.

The purpose of this utility model is achieved in that on hard bus ectosome, is covered to complete with the insulating part segmentation.

Make insulating protective layer at the heavy wall heat-shrinkable tubular body that the straight position and distortion place (stand and bend, put down curved, twist and warping) the employing mixing compound of thermoplastic resin adding surfactant withstand voltage, heat-resisting, that anti-flammability is arranged of bus are made.It is distinguished phase sequence with yellow, green, red trichromatism and substitutes the mopping operation.Coat the temperature indicating look film spot of making the responsive camouflage paint of invertibity with the salt of hydroiodic acid on the body surface, discoloring temperature can be controlled between 60 ℃～90 ℃.Thereby can directly find out the soaking condition of bus, so that the overloading fault on the timely treatment loop tries to avert accidents.In addition, resin is covered by antistatic agent, so there is the electrostatic induction of preventing to gather the effect that dust and dirt produces local corona discharge.

At the junction and the fixing point of hard bus, make insulating protector with Hough intermediate plate withstand voltage, heat-resisting, flame retardant resin die casting.Make the reversible fastening tooth of taking on the Hough intermediate plate body,, just can be fastened on junction or the fixing point, hide interior, so just can reach the security purpose of insulation together with bolt, nut as long as tooth is taken in engagement.

Owing to adopt such scheme, used the simple insulating part of structure, just can all hide exposed bus, make hard bus reach the security purpose of insulation.Its installs that the back is neat and artistic, construction, detect, maintenance is all very convenient, also is an important topic of China's active adoption international standard in the hydraulic and electric engineering industry.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is two insulating part schematic diagrames of the present utility model.

Fig. 2 is an embodiment installation diagram of the present utility model.

(1) a kind of hard bus that links shape among the figure.

(2) heavy wall heat-shrinkable tubular body insulating protective layer.

(3) Hough intermediate plate insulating protector.

(4) the reversible fastening tooth of taking.

(5) temperature indicating look film spot.

Because the utility model has used two insulating parts to coat protection, so want assembled in sequence.

In the enforcement shown in Figure 2, the hard straight position of bus (1) except that junction, fixing point, the heavy wall heat-shrinkable tubular body (2) with corresponding specification coats earlier.The straight position of hard bus (1) is stretched in the cavity of heavy wall heat-shrinkable tubular body (2).Evenly heat the external wall of tubulose with fan heater then; when it is heated to more than the resin softening point; when pour point is following; molecular link will produce the alignment that resets; make cooling at the tube chamber of expanded state by force through shrinkage phenomenon occurring; thereby form and tightly to be coated on the straight position of hard bus (1), just constituted the insulating protective layer at this position.

Again hard bus (1) is fixed on the pillar, selects for use corresponding specification, identical shaped Hough intermediate plate (3) to coat in junction and fixing point.As long as the fastening tooth (4) of taking on the engagement Hough intermediate plate (3), two just fit on hard bus (1), and covering is all sealed together with bolt, nut in the exposed section, have constituted the insulating protector at this position again.

Claims (3)

1, a kind of hard bus insulation protective that improves bus insulating property; be on hard bus ectosome, to carry out fragmented packets with insulating part to cover; it is characterized in that: the heat-shrinkable tubular body is close to coating with straight position, distortion place of hard bus, and the Hough intermediate plate coats with junction, the fixing point engagement of hard bus.

2, hard bus insulation protective according to claim 1 is characterized in that: heavy wall heat-shrinkable tubular body surface scribbles reversible red temperature indicating look film.

3, hard bus insulation protective according to claim 1 is characterized in that: the fastening tooth of taking of making engagement usefulness on the Hough intermediate plate body is positioned at anastomosis, parallel axisymmetric two sides.
