specific Embodiment

[0049] Such as figure 1 , figure 2 , image 3 , Figure 4As shown in , the telemeter is mainly composed of a housing 1, a clamping mechanism, a mutual induction coil and a data collection and transmitting device 13. The mutual induction coil is divided into a fixed mutual induction coil 4 and a movable mutual induction coil 2 . The fixed mutual induction coil 4 is fixed to the housing 1 and cannot move. The movable mutual induction coil 2 can rotate around the hinge, and there is a power storage spring 14 in a compressed state between the casing 1 and the movable mutual induction coil 2 to press the fixed coil 4 to close it. The clamping mechanism includes an insulating control rod 3, a worm screw 5, a worm wheel 6, a fixed sleeve 7, a connecting rod 8, a translation rod 9, a clamping connecting rod one 10, a clamping connecting rod two 11, and a rotating block 12.

[0050] In the initial state, both the mutual induction coil and the clamping mechanism are in the closed ...

Abstract

The present invention discloses a mechanical clamping type high-voltage line load current telemetering instrument. The mechanical clamping type high-voltage line load current telemetering instrument comprises a shell, a clamping mechanism, mutual inductance coils and a data acquisition and transmitting device; the mutual inductance coils comprise a fixed mutual inductance coil and a movable mutual inductance coil; the fixed mutual inductance coil is fixed to the shell; the movable mutual inductance coil is hinged to the shell; a force accumulating spring in a compression state is arranged between the movable mutual inductance coil and the shell; the force accumulating spring can press the movable mutual inductance coil to the fixed mutual inductance coil, so that the movable mutual inductance coil and the fixed mutual inductance coil can be closed; and the clamping mechanism includes a rotation rod, a worm, a worm gear, a fixed sleeve, a connecting rod, a translating rod, a clamping connecting rod One, a clamping connecting rod Two and a rotating slider. The mechanical clamping type high-voltage line load current telemetering instrument has the advantages of structural simplicity and functional diversity. The clamping mechanism does not require a motor, so that the clamping mechanism will not consume power, and the mechanical clamping type high-voltage line load current telemetering instrument can be energy saving and environmentally friendly. Data signals are transmitted wirelessly, research and use can be facilitated.

Description

technical field [0001] The invention relates to a current telemeter, in particular to a mechanically clamped high-voltage line-loaded current telemeter. Background technique [0002] At present, manual measurement uses high-voltage current transformers for on-line measurement, which must be installed in a power failure, with cumbersome procedures and high costs, and it is very dangerous for staff to work at heights. The current telemeter has only appeared in the past two years, and there are mainly two types, one is a clamp-type high-altitude current telemeter, and the other is an electric high-voltage line-carrying current wireless telemeter. [0003] (1) Clamp-on high-altitude current telemeter: [0004] The structure is clamp type, there is no safe anti-falling locking structure, only relying on the spring to make the jaws closed and clamped on the high-voltage line to be tested, in case of wind, it is easy to fall and cause damage to the instrument or even injure the st...
