Abstract:
It is therefore an objective of the invention to provide a terminal block including: an insulating body with a duct and at least one hole formed through a wall of the insulating body, a conductive linking bar in the insulating body for connecting at least one wire respectively passing through the at least one hole, a temperature probe received by the duct and made of transparent and insulating material having a first end and a second end, and a discoloration layer arranged at the first end of the temperature probe having at least a thermochroic layer. At least a portion of the temperature probe is arranged to pass through the duct towards the conductive linking bar so that the discoloration layer at the first end of the temperature probe is closer to the conductive linking bar than the second end of the temperature probe. By having such configuration, the discoloration layer will be heated rapidly thereby in the event of the bar overheating to provide a rapid colour change indicating a fault condition. This makes it more sensitive to the temperature of the conductive linking bar. Besides, the lights reflecting the colour change of the discoloration layer will propagate to the external of the insulating body through the optical path provided by the transparent temperature probe and arrives at the second end portion of the probe, which makes it visible to the eyes of the observer from an external point of view. This allows the image of discoloration layer to be viewed by the observer perceiving a fault occurring.
Abstract:
It provides a surge arrester (1) and its manufacturing method. The surge arrestor (1) includes an active part (10) extending along a longitudinal direction (14) of the surge arrester (1), a first electrode (11) having a first interlocking part (110), being arranged to rest against a first end (100) of the active part (10), a second electrode (12) resting against a second end (101) of the active part (10), wherein the second end (101) opposes the first end (100) in the longitudinal direction (14) of the surge arrester (1), a flexible insulating housing (13), being arranged around an assembly of the first electrode (11), the active part (10) and the second electrode (12), and a second interlocking part (132) formed on an inner surface of the flexible insulating housing (13). The first interlocking part (110) of the first electrode (11) is arranged to fit with the second interlocking part (132) of the flexible insulating housing (13) for preventing relative movement of the first electrode (11) and the flexible insulating housing (13) in the longitudinal direction (14) of the surge arrester (1). The flexible insulating housing (13) includes: a support member (130) mechanically connecting and supporting the assembly of the first electrode (11), the active part (10) and the second electrode (12), which has a plurality of supporting elements (130a,130b) being arranged parallel to the longitudinal direction (14) of the surge arrester (1) and being arranged laterally at sides of the assembly of the first electrode (11), the active part (10) and the second electrode (12), and an insulating expandable part (131) with a plurality of sheds extending outwards, being moulded around the support member (130) and being spaced apart from the assembly of the first electrode (11), the active part (10) and the second electrode (12). Because the support elements (130a,130b) are mechanically connected by the flexible insulating housing (13), by exerting outwards radial force on the flexible insulating housing (13), the cross- section of its inner space is enlarged, thus making it easier to insert the assembly of the first electrode (11), the active part (10) and the second electrode (12) into the flexible insulating housing (13). Besides, the interlocking mechanism ay prevent an undesirable relative movement between the electrode (11,12) and the flexible insulating housing (13) in the longitudinal direction (14).

The first end and at least a part of the connecting portion of the temperature detector is arranged to pass through the duct towards the conductive linking bar so that the discoloration layer on the second end of the temperature detector is farther to the conductive linking bar than the first end of the temperature detector. By having such arrangement, it is helpful to allow the discoloration layer to be viewed by an external observer indicating overheating in the terminal block, thus make it more sensitive to the internal temperature of the terminal block.
