[0003] The general primary part needs to be configured with: poles, vacuum interrupters, disconnectors, voltage sensors, current sensors, live indicators, power supply and other primary components, and used in conjunction with secondary power distribution terminals. The primary components in traditional designs are usually set as independent structures, which are installed on a bracket and connected to the primary cable and secondary signal line to achieve collaborative work, but this method has many disadvantages: 1) Since multiple primary components need to be installed and wired separately, on the one hand, operators are easily affected by the construction site, which can easily lead to equipment damage due to wiring errors; on the other hand, the messy wiring of primary cables and secondary lines affects the appearance of the product, and the wires are prone to interfere and affect each other.

[0004] 2) The size and weight of the entire device increase, and the manufacturing and installation costs increase.

At the same time, the moving contact assembly 2, the vacuum switch control part of the vacuum switch assembly 4 and the isolating switch assembly 8 are installed in the installation cavity 11 of the pole 1, so that multiple components can be integrated into the inside of the pole 1 to complete the integrated integration. Compared with the external arrangement of each structure in the prior art, the pole 1, the moving contact assembly 2, the high-voltage plug-in part 3 of the power supply, the vacuum switch assembly 4, the incoming line voltage sensor 5, the outgoing line conductive rod 6, the outgoing line voltage sensor 7 and the isolating switch assembly 8 can be avoided. Short circuit or grounding fault caused by contact with objects such as tree branches can also be avoided. The hidden danger of burning of the device or related equipment caused by the increase of contact resistance after the above-mentioned structure is rusted can also be avoided. In addition, in the above-mentioned method, a combination of fixed packaging and assembly is adopted, so that all components can be prefabricated in the factory when the switch device is manufactured, that is, the arrangement of the above-mentioned structure, the connection of the lines, the packaging, etc. are realized, so that it is integrated without the need for on-site assembly. This can make the distribution of the above-mentioned structure more reasonable to a certain extent, reduce the volume and weight of the entire device, and reduce its manufacturing cost and installation cost. It also does not require operators to complete a complicated assembly process on site, avoiding wiring errors caused by environmental factors. At the same time, it can also avoid the confusion and mutual influence of various wirings, and can also reduce on-site installation construction time, reduce power outage time, and reduce construction costs.

[0039] Specifically, the integrated switch device also includes a current sensor 100 and a charge indicator 200 fixedly packaged in the injection molding packaging part 12, the lead conductive rod 6 passes through the center of the current sensor 100 and the charge indicator 200, the charge indicator 200 is configured as a cylindrical structure formed by copper winding, and the charge indicator 200 is located in the inner hole of the current sensor 100.

[0040] Furthermore, the pole 1, the high-voltage plug-in part 3 of the power supply, the arc extinguishing chamber 41 of the vacuum switch assembly 4, the incoming line voltage sensor 5, the outgoing line conductive rod 6, the outgoing line voltage sensor 7, the current sensor 100 and the charged indicator 200 can be fixed and packaged at one time using epoxy resin, so that the device has high integration, good insulation and good stability.

[0041] See also Figures 2 to 6 The moving contact assembly 2 includes a double-linked contact finger seat 21, a first through hole 22, a second through hole 23, a first spring contact finger 24 and a second spring contact finger 25; the first through hole 22 and the second through hole 23 are both opened on the double-linked contact finger seat 21; the first spring contact finger 24 is fixedly arranged on the inner wall surface of the first through hole 22, and is electrically connected to one end of the arc extinguishing chamber 41; the second spring contact finger 25 is fixedly arranged on the inner wall surface of the second through hole 23, and is electrically connected to the isolation knife 81.

[0042] Specifically, an annular groove may be provided on the inner wall of the first through hole 22 for accommodating the first spring contact finger 24. Similarly, an annular groove may be provided on the inner wall of the second through hole 23 for accommodating the second spring contact finger 25.

[0043] In order to achieve stable installation of the moving contact assembly 2 , a pre-installed fastener 9 fixedly packaged in the injection-molded packaging portion 12 is also included; the pre-installed fastener 9 is fixedly connected to the double-linkage contact finger seat 21 through a matching fastener.

[0044] Specifically, the pre-installed fastener 9 includes a first fixing nut 91 and a second fixing nut 92, and the first fixing nut 91 is larger than the second fixing nut 92; the connection position of the first fixing nut 91 and the double-linkage contact finger seat 21 is located between the first through hole 22 and the second through hole 23; there are at least two second fixing nuts 92, one of which is connected to the double-linkage contact finger seat 21 at a side of the first through hole 22 away from the second through hole 23, and the other is connected to the double-linkage contact finger seat 21 at a side of the second through hole 23 away from the first through hole 22.

[0045] It can be understood that, in this embodiment, the pre-installed fastener 9 is configured as a first fixing nut 91 and a second fixing nut 92 , and correspondingly, the matching fastener is configured as a screw or a threaded rod to achieve fixed connection of the double-linkage contact finger seat 21 .

[0046] Specifically, the vacuum switch control unit includes an arc extinguishing chamber pull rod 42, one end of the arc extinguishing chamber pull rod 42 is connected to one end of the arc extinguishing chamber 41, and the other end is connected to the vacuum switch operating mechanism.

[0047] For the convenience of explanation, Figure 2 The upper and lower parts shown are the upper and lower parts of the product. It can be understood that the arc extinguishing chamber 41 is essentially a vacuum switch, with a stud for connecting the cable at the upper end and a cylindrical copper rod at the lower end. The cylindrical copper rod is the moving end of the vacuum switch. The copper rod passes through the first through hole 22 set on the double-linkage contact finger seat 21, and the outer wall surface abuts against the first spring contact finger 24 in the first through hole 22, which is used to pass a large current. A threaded hole is provided at the center of the lower end of the copper rod, which is used to be screwed and connected with the screw provided at the upper end of the arc extinguishing chamber pull rod 42. The other end of the arc extinguishing chamber pull rod 42 is connected to the operating mechanism of the vacuum switch. During the operation of the operating mechanism, the arc extinguishing chamber pull rod 42 is driven to reciprocate, thereby pulling or pushing the copper rod at the lower end of the arc extinguishing chamber 41 to realize the separation and connection of the vacuum switch.

[0048] Similarly, the isolating knife 81 is also set as a copper round rod. The isolating knife 81 passes through the second through hole 23 set on the double-link contact finger seat 21, and the outer wall surface abuts against the second spring contact finger 25 in the second through hole 23, which is used to pass a large current. The isolating switch control unit includes an isolating knife pull rod 82, one end of which is connected to one end of the isolating knife 81 (a detachable fixed connection can be achieved by threaded connection), and the other end is connected to the isolating switch operating mechanism. The isolating switch operating mechanism drives the isolating knife pull rod 82 to reciprocate, further drives the isolating knife 81 to reciprocate, and controls the conduction or disconnection between the isolating knife 81 and the first conductive end 61.

[0049] Further, the first conductive end 61 is detachably connected to a stationary contact 60, and the stationary contact 60 includes a stationary contact finger seat 601, a third through hole 602 and a third spring contact finger 603; the stationary contact finger seat 601 is electrically connected to the first conductive end 61; the third through hole 602 is penetrated and arranged on the stationary contact finger seat 601; the third spring contact finger 603 is fixed on the inner wall surface of the third through hole 602; the isolating switch control unit drives the isolating knife 81 to move axially back and forth, so that the isolating knife 81 and the third spring contact finger 603 are connected or disconnected, and when the isolating knife 81 and the third spring contact finger 603 are connected, a current path can be formed.

[0050] In addition, it can be understood that the isolating switch assembly 8 and the moving contact assembly 2 and the static contact 60 are designed as spring contact fingers and a direct-acting reciprocating motion structure (the isolating knife 81 performs linear reciprocating motion along the axial direction), which has the advantages of long operating life and reliable contact compared to traditional rotary external isolating switches.

[0051] See also Figure 1 and Figure 7The high-voltage terminal of the incoming line voltage sensor 5 is electrically connected to the arc extinguishing chamber 41 through a second wire 50 (specifically, it can be a screw at the upper end of the arc extinguishing chamber 41 ), and the incoming line voltage sensor 5 and the second wire 50 are fixedly packaged in the injection molding packaging part 12 .

[0052] Specifically, the high voltage terminal of the outgoing voltage sensor 7 is electrically connected to the first conductive end 61 via the third wire 70 , and the outgoing voltage sensor 7 and the third wire 70 are both fixedly packaged in the injection molding package 12 .

[0053] Furthermore, the incoming line voltage sensor 5 and the outgoing line voltage sensor 7 may be symmetrically arranged about the plane where the central axis of the isolating knife pull rod 82 and the central axis of the arc extinguishing chamber pull rod 42 are located.

[0054] See also Figure 1 as well as Figures 9 to 11 The high-voltage plug-in part 3 of the power supply includes a contact spring fixing nut 31, a first wire 32, a contact spring fixing screw 33 and a contact spring 34; the contact spring fixing nut 31 is electrically connected to the moving contact assembly 2 through the first wire 32, and the contact spring fixing nut 31 and the first wire 32 are both encapsulated in the injection packaging part 12; the contact spring 34 is fixedly connected to the contact spring fixing nut 31 through the contact spring fixing screw 33; the contact spring 34 is arranged in the plug-in port 30, and is used to be electrically connected to the contact electrode of the power supply; the contact spring fixing nut 31 is electrically connected to the moving contact assembly 2 through a wire.

[0055] Specifically, the plug port 30 is configured to be conical with a circular hole in the middle, the contact spring fixing nut 31 is configured at the bottom of the circular hole, and the contact spring fixing nut 31 and the first wire 32 can be fixedly packaged in the injection packaging portion 12 of the pole 1 by epoxy resin, and the threaded hole of the contact spring fixing nut 31 is exposed at the bottom of the circular hole to facilitate threaded connection with the contact spring fixing screw 33 to achieve the installation of the contact spring 34.

[0056] Furthermore, two high-voltage power supply plug-in parts 3 can be provided, and they are symmetrically arranged with respect to the double-linkage contact finger seat 21 .

[0057] It should be understood that the setting of the high-voltage plug part 3 of the power supply can be used in an integrated manner with the power supply, and at the same time solves the problem of high-voltage insulation of the plug interface 30. Specifically, when the contact electrode of the power supply is inserted from the plug interface 30, the contact spring 34 is compressed to form a reliable electrical connection. This method can form an electrical connection in a sealed space, which is beneficial to high-voltage insulation performance and dust and water resistance compared to the existing screw and nut connection form that requires a screwdriver operation hole to be reserved.

[0058] This embodiment also provides a processing technology for an integrated switch device, which specifically includes the following steps: The high voltage plug-in part 3 of the power supply, the arc extinguishing chamber 41 of the vacuum switch assembly 4, the incoming voltage sensor 5, the outgoing conductive rod 6, and the outgoing voltage sensor 7 are fixedly packaged in the injection packaging part 12 of the pole 1; The moving contact assembly 2 , the vacuum switch control unit of the vacuum switch assembly 4 and the isolating switch assembly 8 are installed in the installation cavity 11 of the pole 1 .

[0059] The steps are also included: fixing and packaging a plurality of pre-installed fasteners 9 in the injection packaging portion 12; The moving contact assembly 2 is fixed in the installation cavity 11 by using the pre-installed fasteners 9 and the matching fasteners.

[0060] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
