Transformer oil level thermostat wiring adapter

Abstract

The invention provides a connection adaptor of an oil-level temperature controller of a transformer. The connection adaptor comprises a first housing; and a second housing is connected to the lower end of the first housing. A first opening is formed in the upper end of the first housing; a second opening is formed between the first housing and the second housing; and a third opening is arranged at the lower end of the second housing. A terminal seat and a first sealing ring are arranged at the second housing; and a second sealing ring is arranged at the third opening. A cross-shaped baffle plate is arranged in the center of the terminal seat and passes through the terminal seat; conductive posts are arranged in four separation units of the baffle plate and pass through the terminal seat; and plugging holes and pressing screws are arranged at the two ends of the conducive posts. Therefore, a cable core insulation layer can be protected. Moreover, the wire pressing can be done easily; the routing becomes beautiful; and the work efficiency can be improved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a wiring adapter for a transformer oil level temperature controller. Background technique [0002] Transformers generate heat during operation. To ensure that the transformer oil temperature is within the normal range, a thermostat is required to monitor the temperature of the transformer oil surface. The commonly used thermostat is the BWY-803A series transformer oil surface thermostat, which is mainly composed of elastic elements, capillary tubes, temperature bulbs and micro switches, and has an integrated structure. Because the thermostat temperature package contains precision components, it often breaks down. At this time, the thermostat needs to be replaced as a whole. However, the wiring space in the thermostat case is narrow and the terminals are small. The secondary cable used is a hard core cable. It is serious, which makes the crimping difficult, the wiring is not bea...

Because the thermostat temperature package contains precision components, it often breaks down. At this time, the thermostat needs to be replaced as a whole. However, the wiring space in the thermostat case is narrow and the terminals are small. The secondary cable used is a hard core cable. Major, making crimping difficult, unsightly wiring, time-consuming and labor-intensive to replace; and the cable core is easy to damage the insulation layer, resulting in grounding or short circuit, which poses a safety hazard
