Problems solved by technology

[0002] At present, for coal-fired thermal power plants, it is more likely to be under lower power generation load and operating conditions in the future. The frequency conversion speed control device for the main electric rotating equipment is to solve the problem of low efficiency and power consumption of rotating equipment under load. One of the ways to be too high, but then derived the requirement of supporting the transformation of the protection device for the high-voltage power distribution device, which not only increases the transformation cost, but also involves the transformation of the secondary circuit of the high-voltage power distribution cabinet. , and will also incur higher costs

Embodiment 1

[0029] refer to figure 1 , which is the first embodiment of the present invention. This embodiment provides a manual-integrated high-voltage power distribution cabinet protection pressure plate, including a housing 100 , a pressure plate assembly 200 and a drive assembly 300 . The shell 100 is used as an outer part, the pressure plate assembly 200 inside the protector, the shell 100 is fixed on the user's high-voltage power distribution cabinet, and can be installed vertically or horizontally. When the pressure plate 201 is embedded inside the shell 100 At this time, the protection device of the whole set of protection pressing plate 201 is in the state of power frequency differential protection.

[0030] The two ends of the housing 100 are communicated with each other. The pressing plate assembly 200 includes a pressing plate 201 inside the housing 100 , a movable rod 202 on the upper part of the pressing plate 201 , and a first contact electrode 203 on the upper part of the ...

Embodiment 2

[0033] refer to Figures 1 to 6 , which is the second embodiment of the present invention, which is the same as the previous embodiment.

[0034] The first contact electrode 203 is I-shaped, the first contact electrode 203 is hollow, and the first contact electrode 203 is sleeved on the pressing plate 201 . The first contact electrode 203 is used to connect the positive and negative electrodes of the protection pressure plate 201 when the power frequency pressure plate is put in. It is made of brass and has good conduction characteristics.

[0035] The pressing plate 201 is provided with a first connecting groove 201a, the first connecting groove 201a is correspondingly disposed with the first contact electrode 203, the first contact electrode 203 is sleeved on the pressing plate 201 through the first connecting groove 201a, and the first contact electrode 203 and the pressing plate 201 Surface flush setting. The first connection groove 201a is used to realize the sleeve of ...

Embodiment 3

[0040] refer to Figures 1 to 6 , is the third embodiment of the present invention, which is the same as the previous embodiment.

[0041] The drive assembly 300 includes a guide rod 301, a drive rod 302 and a turntable 303. One end of the guide rod 301 is rotatably connected to the movable rod 202, and the other end of the guide rod 301 is rotatably connected to the drive rod 302. One end of the drive rod 302 is provided with a slider 304. 302 is slidably connected to the turntable 303 through the slider 304 .

[0042]The guide rod 301 is made of brass, which can maintain the connection of the circuit during the movement. The horizontal motion of the driving rod 302 is converted into the vertical motion of the movable rod 202 through the guide rod 301. The driving rods corresponding to the rods 202 are arranged in opposite directions of horizontal movement, that is, the two driving rods 302 can realize the input and cutting operations of the pressing plate 201 through the mo...

Abstract

A manual-automatic integrated high-voltage power distribution cabinet protection pressing plate disclosed by the present invention comprises a shell, a pressing plate assembly and a driving assembly, the two ends of the shell are communicated, and the pressing plate assembly comprises a pressing plate located in the shell, a movable rod located at the upper part of the pressing plate and a first contact electrode located at the upper part of the pressing plate. Second contact electrodes are arranged in the shell, the second contact electrodes are arranged on the two sides of the first contact electrode, and the driving assembly and the movable rod are rotationally arranged. On the basis of a traditional pressing plate, the frequency converter is used in cooperation, and input and cut-out of differential protection in the protection pressing plate can be achieved through a state signal point of the frequency converter.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a manual-integrated high-voltage power distribution cabinet protection pressure plate. Background technique [0002] At present, coal-fired thermal power plants are more likely to be under lower power generation loads and operating conditions in the future. For the main power-consuming rotating equipment, the frequency conversion speed control device is to solve the problem of low efficiency and power consumption of rotating equipment under load. It is one of the ways that is too high, but it also leads to the requirement of supporting the transformation of the protection device of the high-voltage power distribution device, which not only increases the transformation cost, but also the transformation of the protection device will involve the transformation of the secondary circuit of the high-voltage power distribution cabinet. , and also incur higher costs. ...
