Description

Switch-on/off position signal control device of isolating switch operation box

Technical Field

The utility model relates to the technical field of isolating switches, in particular to a switching-on and switching-off position signal control device of an operating box of an isolating switch.

Background

The electric operation box of the isolating switch is equipment for controlling the opening and closing of the isolating switch. When the alternating current and direct current high-voltage isolating switch performs opening or closing operation in place, power is required to be cut off between the isolating switch operating box and the isolating switch. When the high-voltage isolating switch performs opening or closing operation in place, the rotating shaft in the operating box rotates to drive the pressing block on the operating box to contact with the contact of the travel switch, so that the power supply of the operating box and the isolating switch is disconnected to stop the opening and closing movement of the isolating switch, and meanwhile, an auxiliary switch connected with the rotating shaft sends an opening position or closing position signal to feed back the current position of the high-voltage isolating switch, so that the next operation of the electrical equipment is guided, and the running condition of the isolating switch is protected or monitored.

In the related art, the opening position or closing position signal sent by the auxiliary switch is not completely synchronous with the opening or closing position of the conductive part of the high-voltage isolating switch, because when the isolating switch is opened or closed at an opening angle (for example, the rotating shaft of the operating box is a 90-degree rotating angle), the switching angle (generally 75 degrees) of the signal contact in the auxiliary switch is smaller than the opening or closing angle of the isolating switch, so that when the high-voltage isolating switch is opened or closed in place, the auxiliary switch can send the opening or closing position signal within the action angle range. All contacts of the conventional auxiliary switch are closed or opened simultaneously, and different control signals cannot be sent to different devices. With the development of an extra-high voltage alternating current/direct current power grid, the automatic operation of power equipment is continuously improved, the use occasion and the requirement are continuously changed, and the traditional auxiliary switch contact position signal transmission can not meet the requirements of a power grid company on a high-voltage isolating switch and a high-precision relay protection.

The signal control device for the opening and closing position of the isolating switch operation box comprises a driving assembly, a signal trigger piece 30, a mounting frame 50 and a plurality of signal trigger points 70 fixed on the mounting frame 50. The signal trigger 30 is connected with the driving assembly, one end of the signal trigger 30 extends toward the signal trigger point 70, and the driving assembly drives the signal trigger 30 to rotate to a position corresponding to the signal trigger 30 without direct contact so as to trigger different signal trigger points 70 to perform corresponding actions. Specifically, the signal trigger point 70 is an auxiliary switch set in the isolating switch operation box, and different signal trigger points 70 are triggered by the set signal trigger piece 30 to send different control signals to equipment associated with the signal trigger points 70, so that the purpose of sending signals according to equipment requirements is achieved, the continuous change of use occasions and requirements is met, and the problem that in the prior art, the auxiliary switch simultaneously controls a plurality of equipment or devices connected with the auxiliary switch to act simultaneously, and can not send different control signals to different equipment is solved.

Specifically, in this embodiment, the signal triggering member 30 includes a rotating shaft 31 connected to the driving assembly, and a limiting plate 33 mounted on the rotating shaft 31, the driving assembly drives the rotating shaft 31 to rotate and further drives the limiting plate 33 mounted on the rotating shaft 31 to rotate, and the limiting plate 33 rotates to the signal triggering point 70 and is spaced by a preset distance to trigger a signal. The limiting plate 33 is not in direct contact with the signal trigger point 70, but triggers the contact by setting a preset trigger distance, and the signal trigger point 70 is triggered when the limiting plate 33 moves to a range of distance from the signal trigger point 70 within the preset trigger distance. Specifically, the signal triggering member 30 is a proximity switch, the proximity switch is a non-contact switch, when a moving object approaches to the proximity switch within a certain distance range, a signal can be sent, and when the limiting plate 33 rotates to a preset distance near the signal triggering point 70, the signal is triggered by sensing the limiting plate 33.

Preferably, the signal trigger point 70 is a photoelectric switch. The detection device uses the shielding or reflection of the detected object to the light beam, and the synchronous loop is used for switching on the circuit, thereby detecting whether the object exists or not. The object is not limited to metal, and all objects that reflect light (or block light) can be detected.

The limiting plate 33 is mounted on one side of the rotating shaft 31, a plurality of protrusions 35 with different heights are disposed on two sides of the limiting plate 33, and under the rotation change of the limiting plate 33, the protrusions 35 are spaced from different signal trigger points 70 by a preset distance to trigger the signal trigger points 70.

The protrusions 35 of different heights trigger signal trigger points 70 at different positions. For example, the signal trigger points 70 are arranged in a plurality of rows in parallel, the first row is a contact # 1, the second row is a contact # 2, the third row is a contact # 3, the fourth row is a contact # 4, the fifth row is a contact # 5, and the sixth row is a contact # 6.

The distance between the 1# contact and the bulge is set to be minimum, and initially, the bulge firstly reaches the control distance with the 1# contact, and the equipment connected with the 1# contact acts firstly, because the distance between the 5# contact and the bulge is set to be maximum, after the 1-4# contact signals are sent out, the 5# contact is triggered and is switched to be in a state to disconnect the power supply of the isolating switch and the operation box, and the opening or closing operation is completed. Note that the 6# contact is a spare signal contact.

Referring to fig. 3, it should be explained that, for example, the trigger distance D1 set by the 1# contact is 5mm, the trigger distance D2 set by the 2# contact is 4mm, the trigger distance D3 set by the 3# contact is 3mm, the trigger distance D4 set by the 4# contact is 2mm, the trigger distance D5 set by the 5# contact is 1mm, the limiting plate 33 rotates, the protrusion 35 triggers the 1# contact first, and then the protrusions 35 arranged up and down trigger the 2#, 3#, and 4# contacts sequentially as the limiting plate 33 continues to rotate and approach, and finally trigger the 5# contact. Wherein, the contact 5# is power-off control. Therefore, by setting the different trigger distances and the protrusions 35 with different heights, position signals can be generated for different devices according to different requirements, so that the situation and the continuous change of requirements can be met.
