Embodiment Construction

[0044] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0045] Such as figure 1 , 2 As shown, the remote control actuator for opening and closing of the low-voltage switchgear of the present invention includes a box body 10 and an actuator assembly 20 located in the box body 10 . A wire passing hole 101 and a passing hole 102 for the ejector rod to pass through are opened in the lower part of the box body 10 .

[0046] Such as image 3 , 4 , 5, the actuator assembly 20 includes an electromagnet 21, a push rod 22 for touching the switch button of the circuit breaker, a steel column 23 located at the upper end of the push rod 22, and a return spring 24 sleeved on the outside of the push rod 22; The ejector rod 22 is arranged on the axis of the electromagnet 21 and passes through the electromagnet 21. The electromagnet 21 can be activated under the control of the controller and attract the steel colu...

Abstract

The invention discloses a low-voltage switch cabinet breaking-closing remote control actuator, which comprises an electromagnet, an ejector rod used for touching a switch button of a circuit breaker,a steel column located at the upper end of the ejector rod and a return spring sleeving the outer side of the ejector rod. The ejector rod is arranged on the axis of the electromagnet and passes through the electromagnet, the electromagnet is capable of starting and attracting the steel column to move in a direction close to the electromagnet under the control of the controller, and the return spring is pressed against the steel column so as to always give the steel column a force away from the electromagnet. A controller can control the electromagnet coil to attract and return to drive the steel column to reciprocate linearly, so as to drive the ejector rod to reciprocate linearly to touch or leave the switch button of the circuit breaker. On the one hand, the unattended goal of the substation is realized through more scientific and professional automation means; on the other hand, the automation control data of the substation is brought into the data processing system of the smart grid.

Description

technical field [0001] The invention relates to the technical field of power distribution automation equipment and facilities, in particular to a remote control actuator for opening and closing a low-voltage switch cabinet. Background technique [0002] With the advancement of the third industrial revolution, electricity will occupy an increasing proportion in the composition of energy consumption. Due to the scarcity of power transmission resources, the power system has a natural monopoly, and the power system has many unique characteristics. The power system is one of the most complex man-made industrial network systems in the world. Compared with telecommunications companies, the power system covers a wider area and has more access users. All kinds of large and small equipment and household appliances among various power users are connected to the power grid through various voltage levels. Therefore, the grid has the potential to have the most realistic and extensive d...
