The invention discloses a new-type high-voltage breaker handcart which includes a breaker installed on the breaker handcart, an operation button on the breaker handcart operation panel. The new-type high-voltage breaker handcart has characteristics in that: the operation panel has micro-computer colligation protective device, and electric connects with the breaker through secondary socket; the breaker vacuum bubble exterior has a current transformer, signal output port of the current transformer electric connects with the micro-computer colligation protective device; the breaker first contactpoint has a fiber sensor, signal output port of the fiber sensor electric connects with the micro-computer colligation protective device. By using the structure above mentioned, the new-type high-voltage breaker handcart has advantages as follows: 1. the fiber sensor on the breaker first contact point can monitor temperature of first contact point in real time, and avoid contact point overheat toburnout, increase reliability of distribution device. 2. the high-voltage breaker handcart uses integration technology and transformer composite technology, a plenty of connection, thread-checking, detecting and maintaining are not needed between the breaker handcart and switch cabinet, and is convenient for installing and debugging.
Description
technical field [0001] The invention relates to a high-voltage switch cabinet, in particular to a handcart for a high-voltage circuit breaker. Background technique [0002] With the development of science and technology, the automation of power supply and distribution has become one of the main technologies of the power system. At present, the means of realizing the automation of power supply and distribution at the level of 3-3.5KV is combined. [0003] Such as Figure 4 As shown, the 3-40.5KV high-voltage circuit breaker produced by the manufacturer now only has the functions of opening, closing and energy storage. In order to intelligently control the circuit breaker, it is necessary to equip some relevant intelligent devices, such as a microcomputer integrated protection device. , current transformers and connecting copper bars, and put various devices into the corresponding positions of the cabinet, and then carry out a large number of secondary connection lines for cir...
