Embodiment Construction

[0023] Through the following detailed description of the preferred embodiments shown in the drawings, the features and advantages of the present invention can be clearly seen, and the technical solution of the present invention is not limited by the specific preferred embodiments.

[0024] please see figure 1 and figure 2 ,exist figure 1 Independent module 1 and actuator 2 are given in , and figure 1 and figure 2 The housing 12 of the shown independent module 1 is substantially in the shape of a conjoined horseshoe or U-shape or n-shape, molded with insulating material such as plastic. The housing 12 of this shape has two shell cavities, so that the number of groups of switch assemblies has two groups, and each group of switch assemblies includes corresponding first, second, and third microswitches 13, 14, 15, That is, in figure 1 and figure 2 Two first, second and third microswitches 13, 14 and 15 are arranged respectively in the symmetrical shell cavities of the hou...

Abstract

A signal collection and transmission device of position state consists of an independent module including shell to form sliding grooves and a set of switch component having three microswitches with three buttons being extended in sliding grooves; and contact components corresponding to sliding grooves and having the same number as the number of sliding grooves for transmitting and collecting multiples sets of position state signals.

Description

technical field [0001] The invention relates to a position state signal acquisition and transmission device, in particular to a power supply and distribution device for low-voltage electrical equipment such as a withdrawable circuit breaker, a low-voltage drawer switch cabinet, etc. The signal acquisition and transmission of the three position states of separation, test and connection. Background technique [0002] At present, due to the increasing automation of low-voltage power distribution technology, higher requirements are put forward for the monitoring of various signals. [0003] As a power supply and distribution device of low-voltage electrical equipment, such as a withdrawable circuit breaker, a low-voltage drawer switchgear, etc., there are three different position states, namely, the separation state, the test state and the connection state. For withdrawable circuit breakers, when the component under test (also known as the circuit breaker body) of the circuit b...
