Description

A method for switching plugs of multi-function overhauling power boxes

technical field

The invention belongs to the field of electric power construction, in particular to a method for connecting plugs of a multifunctional overhaul power supply box.

Background technique

In order to ensure the safety of power production, when the fault is missing or the equipment is overhauled, the plug of the overhaul power shaft should match the socket in the overhaul power box, and it is strictly forbidden to mix different types of plugs and sockets forcibly. Different substations and different equipment rooms of the same substation use different types of maintenance power sockets, which creates obstacles to the lack of faults and the introduction of maintenance power during equipment maintenance. Maintenance personnel often need to carry several plugs with different types. Two or three power shafts are laborious and laborious, which affects the efficiency and safety of maintenance work.

The present invention solves its technical problem and realizes by taking the following technical solutions:

A method for switching plugs of a multi-function maintenance power box, characterized in that: the specific steps are as follows:

(1) Prepare the special plug for the terminal to be tested;

(2) Install the converter, press the buckle part of the converter firmly, open the converter, and place the special plug for the terminal of the inspection power shaft in the metal groove of the converter;

The converter includes a box cover, box bottom, buckle, plug socket, power plug, wire and metal groove. The box cover is hinged in the middle of one side of the box bottom. The outside of the box cover is covered with an insulating layer, and the bottom of the box and the middle part of the open side of the box cover are relatively made/fixed with snap buttons; two cylindrical plug seats are installed longitudinally on the upper inner side of the box bottom, and the two plug seats A power plug is installed in the middle part, and one end of the two power plugs protrudes out of the insulating box, and one end of the two power plugs in the insulating box is respectively connected to a metal groove through a wire, and the two metal grooves are fixed at intervals symmetrically. At the lower part of the inner side of the bottom of the box, the special plug of the terminal on the axis can be installed in the metal groove of the universal plug by opening the snap button;

(3) The converter is closed, and the bottom of the box and the lid of the box are relatively fastened;

(4) Adjust the plug specifications. According to the different types of sockets in the station, adjust the two-pole or three-pole plug of the converter. The plug seat is vertically hinged on the upper part of the bottom of the box. The matched teeth rotate the power plug to drive the teeth to rotate to adjust the matching type of the power plug.

Moreover, a spring is installed in the metal groove, and a plastic gasket is fixed in the box cover corresponding to the position of the metal groove. When the box cover is fastened with the bottom of the box, the plastic gasket and the spring press the terminal from both sides. The special plug and the metal groove ensure that the circuit part is in good contact.

Advantage and positive effect of the present invention are:

1. The converter used in this method is box-type, with snap buttons on one side, which can be quickly and flexibly installed and removed to repair the special plug for the terminal on the power shaft, which is convenient and flexible to use.

2. In the converter of this multi-function overhaul power box plug transfer method, in addition to the metal sheet, a spring is installed in the metal groove of the special plug for the terminal post, so that the special plug for the terminal post can be connected with the multi-functional overhaul power box plug. The transfer method The internal circuit is in close contact, and there will be no bad contact.

3. The two-stage plug part of the multi-functional overhaul power box plug transfer method uses gears, and the rotating plug drives the gears to rotate, so that the plug can be applied to two-stage and three-stage sockets, which increases the convenience of use flexibility.

4. The present invention is a plug-connection method for a multi-function overhaul power box with simple structure, easy manufacture, safe and convenient use, and fast and trouble-free installation. Using this method can improve work efficiency and increase the convenience of installation and use.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

A method for switching plugs of a multi-function maintenance power box, the specific steps are as follows:

(3) Prepare the special plug for the terminal to be tested;

(4) Install the converter, press the buckle part of the converter firmly, open the converter, and place the special plug for the terminal of the inspection power shaft in the metal groove of the converter;

The converter includes a box cover 1, a box bottom 9, snap buttons 6, a plug seat 4, a power plug 2, a wire 5 and a metal groove 8. The box cover is hinged in the middle of one side of the box bottom, and the box bottom and the box cover are relatively buckled to form a Box-type structure, the bottom of the box and the outside of the box cover are covered with an insulating layer, and the middle part of the opening side of the bottom and the box cover is relatively prepared/fixed with a snap button; the unfolded structure is shown in Figure 1, the upper part of the inner side of the box bottom Two cylindrical plug sockets are installed longitudinally, and a power plug is installed in the middle of the two plug sockets. A wire is connected to a metal groove, and the two metal grooves are symmetrically fixed at the lower part of the inner side of the box bottom; when it is necessary to convert the plug of the maintenance power shaft, the special plug 7 for the terminal post on the axis can be installed on the universal plug by opening the buckle. inside the metal slot of the plug.
