Abstract
A protection door of an excitation power cabinet comprises a transparent door body, wherein one end of the transparent door body is hinged with the excitation power cabinet through a hinge to form an instant-opening structure, and a magnetic adsorption piece and a sealing strip are arranged on the edge of the transparent door body; after the transparent door body is closed, the transparent door body is fixed and sealed through the magnetic adsorption piece and the sealing strip. The utility model provides a pair of excitation power cabinet guard gate has both solved the difficult problem of power cabinet resistance-capacitance absorbing device temperature measurement, has solved the difficult problem of silicon controlled rectifier internal insulation baffle inspection again.
Description
Technical Field
The utility model relates to a guard gate, especially an excitation power cabinet guard gate.
Background
The main equipment in the power cabinet of the hydropower station excitation system is provided with a capacitance-resistance absorption device, a silicon controlled rectifier and a fan, wherein the capacitance-resistance absorption device in the power cabinet is generally sealed by a metal plate with a cabinet door, the silicon controlled rectifier rectifying device is sealed by a transparent organic glass plate with the cabinet door, and the power cabinet heat dissipation fan is arranged below the silicon controlled rectifier.
The excitation power cabinet has the following two disadvantages in actual operation:
1. resistance-capacitance absorbing device generates heat seriously in normal operating process, and the temperature can reach about 150 ℃, for preventing that equipment operating temperature is too high and damage, need carry out periodic temperature and patrol and examine, nevertheless because resistance-capacitance absorbing device seals with preceding for the cabinet door protection steel sheet and keeps apart, can't directly carry out the temperature measurement from the power cabinet openly, can only measure the temperature through opening a cabinet back door, not only the temperature measurement degree of difficulty is big, and the cabinet rear side of twining is naked positive pole copper bar, operating personnel easily takes place the high voltage risk of electrocuting.
2. In the long-term operation in-process, the insulating barrier between the power cabinet silicon controlled rectifier device can take place the condition such as ageing, damage, damaged insulating barrier drops and can block up the radiator fan air outlet apron of below, leads to the unable normal start of fan, nevertheless because the silicon controlled rectifier is kept apart with the organic glass board with the external world, and the set screw is numerous, and maintainer is extremely inconvenient when the inspection, change silicon controlled rectifier insulating barrier and silicon controlled rectifier and clean, consumes plenty of time and manpower, seriously influences work efficiency.
Disclosure of Invention
The utility model aims to solve the technical problem that a protection door of excitation power cabinet is provided, both solved the difficult problem of power cabinet resistance-capacitance absorbing device temperature measurement, solved the difficult problem of silicon controlled rectifier internal insulation baffle inspection again.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a protection door of an excitation power cabinet comprises a transparent door body, wherein one end of the transparent door body is hinged with the excitation power cabinet through a hinge to form an instant-opening structure, and a magnetic adsorption piece and a sealing strip are arranged on the edge of the transparent door body; after the transparent door body is closed, the transparent door body is fixed and sealed through the magnetic adsorption piece and the sealing strip.
The transparent door body comprises an insulating frame, and organic glass is embedded in the insulating frame.
The magnetic adsorption piece and the sealing strips are consistent in thickness and are alternately distributed on the insulating frame far away from one end of the hinge, and the sealing strips are fully distributed at other positions of the insulating frame.
The magnetic adsorption piece is a magnetic strip sticker.
The utility model relates to an excitation power cabinet guard gate has following technological effect:
1) through replacing the metal sheet with transparent organic glass guard gate as resistance-capacitance absorption device's baffle, only need open power cabinet qianmen, the operating condition of observation resistance-capacitance absorption device that just can understand measures its real-time temperature value with the temperature measurement rifle. The risk that the maintenance personnel open the back door to patrol and examine the temperature measurement operation degree of difficulty is big, the risk of electric shock risk is high when effectively having avoided excitation power cabinet when the operation.
2) And the accessible opens the door, and more convenient observation power cabinet silicon controlled rectifier between insulation barrier has or not the damaged condition, in time discovers the problem, avoids the insulating baffle damage between the silicon controlled rectifier to drop, leads to the unable normal opening of radiator fan of below.
3) When the excitation system is overhauled and maintained, the realization that can be quick is to work such as data measurement and cleaning of resistance-capacitance absorption device and silicon controlled rectifier, saves a large amount of manpowers, improves work efficiency.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic view of the present invention.
Fig. 2 is a schematic diagram of the middle excitation power cabinet of the present invention.
In the figure: the transparent door body 1, the magnetic adsorption piece 2, the sealing strip 3, the insulating handle 4, the hinge 5, the metal frame 6, the resistance-capacitance absorption device distribution area 7 and the silicon controlled rectifier device area 8.
Detailed Description
As shown in fig. 1, an excitation power cabinet protective door comprises a transparent door body 1, wherein the transparent door body 1 comprises an insulating frame, and organic glass is embedded in the insulating frame. The size of the transparent door body 1 is consistent with that of the metal frame 6 of the excitation power cabinet. One end of the transparent door body 1 is hinged with the excitation power cabinet through a hinge 5 to form an instant-open structure, a magnetic adsorption piece 2 and a sealing strip 3 are installed at the edge of the transparent door body 1, the thicknesses of the magnetic adsorption piece 2 and the sealing strip 3 are consistent, the magnetic adsorption piece and the sealing strip 3 are alternately distributed on an insulating frame far away from one end of the hinge 5, and the sealing strip 3 is fully distributed at other positions of the insulating frame. After the transparent door body 1 is closed, the transparent door body is fixed and sealed through the magnetic adsorption piece 2 and the sealing strip 3.
The magnetic adsorption piece 2 is a magnetic strip sticker. Thereby facilitating installation.
The working principle and the process are as follows:
1) and detaching the metal protective baffle outside the resistance-capacitance absorption device of the excitation power cabinet and detaching the organic glass protective baffle outside the silicon controlled rectifier device.
2) And an organic glass door plate which can block the resistance-capacitance absorption device and the silicon controlled device is used as a protective baffle of the resistance-capacitance absorption device and the silicon controlled device of the power cabinet.
3) Fixing the organic glass door plate on one side of the metal frame of the disc cabinet by using two hinges to serve as a glass protective door;
4) the proper amount of magnetic stripe subsides are pasted in the border department of glass guard gate, can make the fine absorption of glass guard gate on the dish cabinet, can guarantee again that the glass board can conveniently open under the effect of human power.
5) And the soft sealing strip with the same width and thickness as the magnetic strip is pasted at the edge of the glass protective door, so that the glass baffle and the metal frame of the disc cabinet form a sealed environment to ensure the heat dissipation effect of the heat dissipation fan.
6) And an insulated door opening handle is arranged on the glass protective door, so that the door can be opened conveniently.
