DXN-G Inductive Charged Display

In fully insulated equipment such as cable branch boxes and ring main units, due to the fact that all live parts are fully insulated, it is impossible for operators to determine whether the lines are operating normally. In response to this situation, we have developed a live indicator specifically designed for fully insulated equipment, which can be installed on Cooper Corporation and other domestically produced cable connectors in the United States. Remind operators and maintenance personnel whether the circuit is live based on the flashing status of the indicator light.

Principle:

At the testing point, the electric field energy of the charged equipment is sensed. When the electric field energy accumulates to a certain voltage, the display light of the charged indicator turns on and flashes. The flashing frequency varies with the change of system voltage.

Usage conditions:

1. Can be installed on test points of 200A or 600A cable heads.
2. The indicator is fully insulated and sealed, suitable for various climates.

Installation steps for DXN-G inductive live display:

1. The live indicator can be installed when the cable head is live. Generally, the circuit and cable heads should be disconnected before installation.
2. Use an insulated operating rod to remove the protective cap from the cable head test point.
3. Clean and dry testing points. Lubricate the inner surface of the indicator shoe with silicone grease.
4. Hook the operating hole of the indicator with an insulated operating rod, insert the live indicator into the testing point, and rotate it to the appropriate position.
5. After the line is re energized, the indicator light of the live indicator starts flashing, indicating that the line is live.

3. Structure Overview The sensors and displays of the display device are connected through external wires to form a capacitive voltage divider circuit (see schematic diagram in Figure 1)
3.1 Sensors The sensor is made of pillar insulator type and embedded with high-strength dielectric functional material to form a core rod capacitor C1. One end of C1 is connected to the high-voltage bus through an upper flange, and the other end of C1 is connected to the lower end (secondary terminal) of the sensor (see Figure 2). The external structure of the sensor is made into different heights and various umbrella skirts according to the matching requirements (as shown in Figure 4-7). According to installation requirements, the upper flange is made with single screw holes, double screw holes, and four screw holes (specific hole diameter, hole spacing, and hole number are shown in Table 2). There are two types of external insulation structures for sensors: a. The sensor is made of an outer insulation sleeve made of high-voltage porcelain cloth, with a high-voltage capacitor C1 buried in the middle, and its model is CG1 (see Figure 2). b. The sensor is made of outer insulation sleeve and high-voltage capacitor C1, made of SMC material with flame retardancy and hydrophobicity, and made of silk. Its model is CG3 (see Figure 3).



3.2 Monitor The display functions include prompt type and forced type. The prompt type has single display (i.e. three sensors with one display, wiring principle shown in Figure 10) and dual display (i.e. three sensors with two displays, wiring principle the same as single display), with the two displays installed on two different sides of the switchgear. Warning neon lights are not allowed to rest. Compulsory type: It not only has all the functions of prompt type, but also uses pumping signals to control electronic switches and cooperates with electromagnetic locks to perform compulsory locking. When only one phase of the three-phase circuit is charged, the electromagnetic lock cannot be unlocked. The direct key switch in the monitor is used to select the working and resting status of the neon lamp. When the neon lamp is in a resting state, the strong wire locking circuit cannot be unlocked (see wiring principle in Figure 11). Note: Type I displays come in two types: prompt type and forced locking type. The Type II monitor only has a prompt type and does not have a forced locking function. 4. Appearance and installation dimensions 4.1 The appearance and installation dimensions of the sensor are shown in Figure 4-7 and Table 2.

Function of the power verification button:

1. When the high voltage side is powered off, press the power test button, and the A, B, and C indicator lights that display high voltage live should not light up;
2. When the voltage at the high voltage end reaches 15%~<65% of the rated phase voltage, press the power test button, and the A, B, and C indicator lights that display high voltage charging will begin to indicate the charging status of the high voltage end respectively; (See Figure 2 for the wiring diagram used in conjunction with the voltage sensor).
In addition to the above functions, the Q-type voltage indicator can also achieve the following: when any phase voltage in the three-phase high-voltage bus reaches 65%~100% of the rated phase voltage, the electronic circuit control relay output contact J opens and is in a forced locking state;
(Rear view of terminals 3, 4 or K1, K2 in the wiring diagram). When all three phases are not charged, �� the secondary working power supply is normal, the output contact is closed, and it is in an unlocked state;
�� The secondary working power supply is disconnected, the output contact is open, and it is in a protective locking state.
Note: Status 3 and 4 belong to the indicator protection state. When the indicator loses its working power supply, regardless of whether there is voltage at the high voltage end, the relay will be locked
The output contact is always in the disconnected position.

2026-6-13 18:32:32

The GSN series indoor high-voltage live display device is suitable for indoor high-voltage electrical equipment with an AC frequency of 50Hz and a nominal system voltage of 3-35KV. It is used to reflect the live status at the device location and can forcibly lock the switch door and handle to prevent misoperation and entering the live interval, achieving the purpose of preventing errors.

Structural features:
The indoor high-voltage live display device consists of two parts: a sensor and a display, which are connected by outdoor wires as a whole. The sensor is an epoxy resin cast pillar insulator product, and the voltage sensing core rod is cast inside. Its shape can be made into pillar insulators of different heights, sizes, and skirts, and can be used as supporting insulators at the same time. There are two types of displays: prompt type (T) and forced type (Q). The prompt type is used to reflect the live status of the circuit, while the forced type not only has a display function, but also a forced locking function, thereby improving the anti misoperation performance of the supporting products. The forced type uses electronic switches to control electromagnetic locks and achieve forced locking. Voltage indication and forced locking operation are both controlled by the same high voltage signal, but the circuit system is independent and does not interfere with each other. As long as the high voltage circuit is live, even if the display circuit and locking circuit fail simultaneously, the electromagnetic lock is still in the locked state.
